>It's pretty clear that it was painted by someone called Peter Doige, who has nothing to do with Peter Doig.
I noticed the extra "e" on the painting too. Either that is common for Peter to sign, he changed his name to drop the "e", or he forgot how to spell his own name when he was 17. Or someone forged his name as a signature onto the painting but didn't know how to spell "Doig" and didn't bother to look it up hoping they could pass the painting off for millions of dollars.
