LT, all you have to do is put your signature on that artifact to make it really valuable.
I once heard a story about Spanish painter Salvador Dali, it may of course be just a myth, but it is interesting:
Salvador Dali was invited to a dinner, a reporter came by and asked him: "what is art?", Dali answered: "art is Dali", the reporter asked him to explain, so Dali took his cloth napkin, picked up ketchup and mustard and poured some over the napkin, he asked the reporter: "what is this?", the reporter said: "it's a mess", Dali said: "you are right", then he took out a pen and signed on the napkin, picked it up and said: "now it's a Dali"...
