I bet the original is actually worth A LOT of money by now as a pop culture relic of sorts. No kidding. I get a kick out of it everytime I see it, honest.
I have to somehow photograph and post a painting by a friend of mine who is quite well known. His paintings go for lots of money (justifiably). One of the two that I bought from him is not too far from yours, just painted differently. You will be shocked by the similarities.
