Can anyone vouch for this ebay seller? He has a lot of signed vinyl for sale. Some of which is pretty difficult to obtain. He says he is a JSA approved seller. See following link to an example.
This seller is pretty good. Not everything they sell is JSA authenticated. I strongly suggest if you are not certain about a specific item, ask. I do not know REO Speedwagon signatures so cannot help you on this one.
JSA on modern autographs don't know half the time what they are doing. I've seen multiple items by "scagallery" them that don't look right. These 2 items I don't like, they look funky to me. The Jessica has a shot at being a rushed authentic autograph of hers but I still wouldn't want it. The Bruce is probably real but I've never seen "Willis" done like that.
