The little diecut Kinney Novelties (N228-3) are actually fairly common, but there are either 25, 50, or 75 different (3 series) so finding the baseball one is a bit tougher. I see about 4-6 of the baseball ones a year on eBay.BTW Leon, the type 1 Kinney cards (all round) are thicker and have 25 designs. And the type 2 are round with colored borders (there is a complete set of the N228-2 round cards on eBay right now).The baseball one (above) is a type 3 like these below.All these above N228-3 diecuts are on eBay right now.
