Something you might not know about webcomic artist John Allison (me) is that he throws away 2/3 of paintings he does in blind fury. Here's one that made it to the blog, the foggy limbo between the wheelie bin and eBay. The price I've been able to sell things for on eBay has actually decreased steadily over the years, as my novelty declines and the market floods with the 6 paintings I have ever sold.
Yes it is painted on the bottom of a box and stands 57cm high. The exact same height as Gandhi! I would add that because I seem to do the exact same painting over and over again with only minor variations, the marketplace is right about me.
