Recently I have noticed an increase of UK quad reprint / copies selling on EBAY they look ok and are a full 30 x 40 ' . My question is it it illegal? At the moment it is not a big problem detecting these copies. 20 years down the line when they are ( worn in ) could cause all sorts of problems for new collectors or people that just ain't up to scratch. I know there are loads of fakes & copies out there but I think it is time this was made illegal if it is not already. The size would be the first and easiest thing.
