I'm pretty sure it's real because it came with a JSA cert but unfortunatly whoever got it certed got the sticker put on the back of the check. I've never seen this color JSA sticker either but I've never had a check that was authenticated so maybe it's the color they use for that? Anyone familiar with HOF Joe Sewell and former Alabama football player and HC of baseball team in the 60s ? I know Tuscaloosa is spelled Tuskaloosa but I looked all that up and it checks out (no pun intended) here are some pics front and back...not the best pics but if you click on them you will get a zoom up. thanks for any advise (I got it free because the person knew I am a huge Yankee fan and UA supporter)
