I love hidden treasure on ebay...I got this postcard of Billy Sunday playing baseball in a big stack of real photo postcards on ebay...there was no mention of Sunday in the listing, but I could clearly see the "W.A Sunday" on the card in one of the pictures. Total cost of the lot was $60 - I ended up relisting just two of the postcards of a horse driven popcorn wagon and got $150 for the pair.I also got a baseball certificate signed by Kennesaw Landis that wasn't even mentioned in the lot of baseball ephemera that I won for a whopping $5. I have never sent it in to be authenticated, but everyone I have shown it too thinks it is real.I won two snapshot photos of a game at Comiskey c1930 for $10 and when I got them in the mail one said "Ruth at bat" on the back and the other said "Gehrig at bat. I paid only $10 for those...they may not be worth a whole lot, but it was a nice surprise and certainly treasure to me.
