Back in 2014 I bought a pack of Topps Wacky Packages Chrome Stickers (see it here). There was one baseball related card in the pack. Now, Topps has a whole Wacky Packages set devoted to baseball. And it's a hoot. I bought one blaster and I may go get another. I'm only going to post my favorites lest I have my readers groaning too much.
The first 60 stickers feature every MLB team, two stickers for each. Here's my favorite team sticker.
The back of each sticker is 1/9th of a puzzle depicting one of the cards in the set. This one is for Giants Magic Beans. I didn't get enough cards to show more than 4 or 5 of the backs together.
A number of stickers show minor league teams, one card per team.
And finally, perhaps my favorite.
Of course its can't be a baseball card product without multiple parallel sets. I got several of the "Gray" and "Green Turf" parallels. There are apparently "Gold" and "Sepia" ones as well. Here's a Green Turf one so you can see the Giants Magic Bean card in its entirety.
