'I get stuff sent from all over the world, especially Japan,' he said. 'It's good quality, a lot of it, but there is too much and I just don't have room. I've filled up the attic and getting a big cardboard box up there is now very difficult, in fact it's a nightmare.'
Briggs hope to sell the items, which he will sign, on EBay.
'We're starting with one item to see if it will work: a Snowman toy holding a tiny teddy bear, which I've signed. It's very well made, like Steiff teddy bears, and I can't remember if we've said £50 or £150. There are mad collectors out there who will buy anything with signatures. If it works, we hope to put more on and raise money for Great Ormond Street Children's Hospital.'
