Well, maybe not but his 1/1 cut signature from 2007 Allen & Ginter is. Someone put it up on eBay but only after defacing it (writing all over it) to make some kind of statement. Look, I live in South Florida, my wife is Cuban, and I am in no way a supporter of Fidel—but why? Why would you take an authentic autograph of one of the most notorious men of our lifetime and destroy it to make a statement? If you really wanted to make some kind of statement, sell the card in pristine condition and take your $7,000-$10,000 and make donations to people in need, here or in Cuba.
Whatever you intended on doing, you failed. The auction was pulled from eBay. Now all you are left with is a worthless card and more eBay fees. Viva la revolucion? Not likely.
