OK, now what do I do with it ? FAKE drawing

This is NOT an original Johnny Hart drawing of the famous Fat Broad with a club, it is a fake I bought from The Gallery on Baum, Pittsburgh PA on eBay. An astute expert alerted me that it was a fraud, by verifying his suspicion with Johnny Hart Studios. I bought this and another FAKE drawing from The Gallery on Baum and when I contacted them they did not question or dispute that they were fakes, but immediately refunded my money. I learned a lesson on these.
