Amazing postcard signed and inscribed by Hall of Famer Harry Hooper on the front, personalized to hobby pioneer Dick Dobbins.  On the reverse, Hooper sketched out his family tree, writing the name "Harry Hooper" four times, and the last name "Hooper" an additional 12 times.  Has a player written his name so many times on the same postcard?  Clean card, with legible blue ink signatures and family detail on the reverse.  LOA from James Spence Authentication.
