Antiques Roadshow expert Gordon Foster has revealed how one of his most memorable finds came from a show in St Andrews.

Foster, who has been involved in the trade for 40 years, is set to cast his eyes over Glasgow heirlooms as the show heads to Kelvingrove Art Gallery and Museum next week.

The 50-year-old joined the Antiques Roadshow in 2006 and says anticipating the unexpected is what keeps him interested.

His most memorable find is an enamelled brass cross made by one of the Glasgow Girls art group that appeared at a Roadshow in St Andrews in 2011. He said: "It was made for a private family and is a personal religious item so it wasn't of great value but it was a beautiful object, made in the early 20th century and just a real joy to see."

Filming for the 37th series of the show will take place in Glasgow next Thursday. The doors open at 9.30am and close at 4.30pm. Entry is free.

Some of Britain's leading antiques and fine arts specialists will be on hand to offer free advice and valuations to visitors.

Foster said: "We are surprised with something new every time we do the Roadshow but I'm particularly excited about Glasgow for the chance to see silver in the Glasgow style.

"With Charles Rennie Mackintosh, at the turn of the 19th century, the style became much more clean and minimalist.

"Art really flourished in the city at this time so we don't know what surprises might turn up. I'm very much hoping to see some Celtic style items."

As one of the UK's largest seaports, valuers from the hit BBC show are expect to seeing items from all over the world.

The city is also renowned for the Scottish School and the Glasgow School, giving experts the chance to see painting, ceramics, furniture, textiles, jewellery, glass and silver - not to mention the work of Charles Rennie Mackintosh.
