Art On A Postcard are having a charity auction, artists are anonymous, except when they are not. I was invited due to being in the RA Summer Exhibition and so entered three postcards, but I cant tell you which ones they are! I'm not sure how long the auction runs for, but when it's done (and hopefully I've raised some money for charity) then I can put the pictures here. Here's a link to the site.
