I learned about this issue about 3 1/2 years ago when someone posted a couple of lots of these on eBay. Unfortunately for me, there was a Bernie Williams in the lot, so I wasn't about to fight the deep pockets of a Bernie collector. Thankfully, as often happens, if one waits long enough, and is ready with a saved search on eBay, things come back around, and now it resides in my collection!
Presumably these were a stadium giveaway, but none of my newspaper archive resources cover Columbus in the 1990s, so that is only speculation. I am not entirely sure whether the signature is genuine, or just part of the photo. In the photos on Worthpoint, several of the signatures from the original lot overlap the white part of the photo, so that would imply they are real. The photos measure 3 1/2" x 6 7/8" and are printed on photo paper and were sponsored by local camera shop, Cord Camera & Video. A similar set was also issued in 1993, but I don't know whether or not it contains a Meulens.
