An online collectors’ community is coming offline to appear at the Barry Potter Fair at Sandown Park in Esher this Saturday.

And the fast-growing Collectingfriends.com will be bringing some special guests with them to what is one of the biggest collectors’ fairs in the country.

Among the guests are Airfix “guru” Arthur Ward, who will sign copies of his new book Classic Toys as well as Radio 4 presenter Peter Donaldson, who will talk about his blow lamp collection, and militaria supremo Richard Ingram, who promises to come kitted out in a suitably rare costume.

The fair is open from 10.30am until 4pm and admission is £4.50 for adults, £4 for senior citizens and £2 for children.
