I've got the exact same Kangaroo Kid auto incoming - I can't wait to receive it having seen your high quality scan of the card! I got mine for $20 plus $3 postage which I think is a bargain for a player who doesn't sign that much (and who's cards tend to be ugly). I like Private Signings cards because they feature some rare autos, e.g. Cunningham, Twyman, etc.
