I've had a cheap picture very similar to this for a long time. Unless the original artist used a pseudonym I'm assuming it's an unlicensed knockoff. Signature looks like "Jons/Jones[?] 91." I won't link to it, but I found an eBay listing for it and the seller said they won it at an amusement park so that's probably where I got mine.
Sorry for low-quality scan, tried to fix blurriness but no luck so far.
