These cards were issued in mid-November but I didn't see any in my local Target until the other day. I bought 6, 5-card packs at $2.99 each. 4 of the 6 packs had an insert card. I'm not a pack searcher, so I just grabbed the top 6 packs in the box. When I got them home, I noticed that one pack was noticeably thicker than the others. What special goodness was hidden there? What that pack had, the others didn't, was a 3-card thick slab of white cardboard. There aren't actually any relic cards in the release so I wouldn't expect any thicker cards. Was Panini trying to decoy pack searchers?
Anyway, the cards are nice. Panini still doesn't have a license from Major League Baseball so it must have been a challenge to find photos of Hall of Fame players which didn't show team logos. I suspect there may have been some unobtrusive photoshopping going on as well. The cards have a nice glossy finish on the front and a nice design.
As I was leaving the store I thought that there had to be a Mike Schmidt card in the set. The first pack I opened had this card right on top.
