It has a substance, though, for Pat Woods. The author and historian sits in the Scottish Football Museum in Hampden as the curator wheels in a buggy carrying two crates. This is the official Woods Lisbon archive, donated by the former librarian. It includes tickets, programmes, photographs and match reports and analysis from a variety of European newspapers.
It is not quite accurate to call it his life's work. Woods, after all, was approaching 21 when he made his first trip abroad to watch the 1967 European Cup final in Lisbon.
"It was a pilgrimage, an adventure," says Woods and it sparked an interest far beyond football. Woods became a lover of Paris and his annual trips to the French capital have been spiced with visits to the Bibliotheque Nationale. There he researched that day of May 25 assiduously, drawing information and comment from newspapers.
His crates have been filled, too, with purchases from ebay. The treasure chest is full of jewels but Woods has no favourite piece, not the programme, not the ticket not even the photograph of the team that not one Lisbon Lion can remember being taken moments before the game with the team bus in the background.
"I just enjoy reading all of the stuff and I like it when others derive some pleasure too," he says, adding that Charlie Gallagher, the inside forward whose corner kick led to Billy McNeill scoring the winning goal against Vojvodina in the quarter-finals, had visited Hampden to renew old memories in the company of the Woods archive.
The Lisbon 1967 trip stretched to 10 days for Woods as he travelled across Europe by train, arriving in Lisbon on the Tuesday and leaving on the Sunday after the final.
He accepts there will still be memorabilia he cannot conceive of, trinkets that he cannot add to this trove but adds there is nothing that he feels he craves desperately.
Woods, who has since attended four European Cup finals, has just one item he wants to source.
"I would love to be back at another European Cup final in Lisbon," he says. "So that search continues."
11 A writer from the Italian newspaper Corriere Sportivo, sent to interview Sean Connery in Rome - where he was relaxing after filming You Only Live Twice, the latest in the James Bond series - found the Scottish actor was more interested in talking about the European Cup final. "To hell with James Bond ," he told his interviewer. "Let's talk about Jock Stein. I sent him a telegram telling him he was the pride of the Scottish race. There is a touch of the magician about him, you know".
10 Celtic were the fourth Scottish side to make the semi-finals of the European Cup. Celtic's debut in the tournament (season 1966/67) took place 11 years after the inception of the competition. In the intervening years five Scottish clubs had preceded the entry of the Parkhead side: Hibernian, Rangers, Hearts, Dundee and Kilmarnock. Hibs (1956), Rangers (1960) and Dundee (1963) reached the semi- finals.
9 The trophy which Billy McNeill was the first captain to lift was designed and created in the studios of Stadelmann's, a Bernese family firm, at the request of UEFA . It was a replacement for the original trophy which had been handed over in perpetuity to Real Madrid after their sixth triumph in the competition in 1966. UEFA laid down three specifications: the trophy handles had to be such as made it easier to lift; that there should be enough room inside to cater for three or four bottles of Champagne for the winning team's celebrations; and the trophy should be "stately in size and find favour in all parts of Europe."
8 The final was not played in Lisbon but in Jamor in the Estadio Nacional. Despite the amphitheatre's idyllic setting, some six miles outside the city in the pinewoods of the Valley of Jamor, it was regarded as being obsolete because of its lack of cover for spectators and its poor press facilities. A stand had to be built to accommodate journalists. The Lisbon Lions should therefore be known as the Jaguars of Jamor . . .
7 A dozen foreign journalists were canvassed by the Scottish Sunday Express with regard to the outcome of both the European Cup and European Cup-Winners' Cup finals. In respect of the former, seven opted for a Celtic victory, two for an Internazionale win, and three were undecided. One journalist predicted accurately the scores of both finals: Ljuba Vukadilovic of the Belgrade daily Politika, went for a 2-1 Celtic victory and a 1-0 defeat for Rangers by Bayern Munich.
6 Umberto II, the last king of Italy, was a guest of honour at the final. He had reigned for only 34 days before abdicating in June 1946 after losing a referendum on the survival of the monarchy.
5 A case of mistaken identity delayed the presentation of the trophy. Such was the chaos in the Celtic dressing room that an official sent to summon McNeill to collect the trophy was "shown the door" on three occasions before it was realised who he was.
4 On the journey home from Lisbon, Tommy Gemmell's fiancée (Anne Deas) declined an offer of £500 (a small fortune) for the green-and-white hooped coat she was wearing. Jock Stein is said to have told her that she was "mad" not to accept it.
3 Rangers manager Scot Symon told an Italian newspaper: "I will be a Celtic fan on Thursday. Celtic are a thousand times stronger, both in defence and attack, than Inter." Symon duly sent Stein a telegram after the final: "Congratulations on clean sweep. You have done it, Jock. Well done."
2 Bob (later Sir Robert) Kelly, Celtic's chairman, captain McNeill and manager Stein all played for Blantyre Victoria. They were also all centre-halves.
1 In the event of a draw, even after extra time, the final was scheduled to be replayed at the same venue and time two days later (a Saturday). Should the replay have ended in a draw, even after extra time had been played, the destination of the trophy - hard though it is to comprehend nowadays - would have been decided by the toss of a coin.
