To be honest I had no idea these existed as I didn't dip my toes in the collectible cardboard pool until late 1990. However the pack was cheap so I thought I'd give it a try.
As the pack declared, these cards were also stickers. With the "peel" in each corner, I imagine the sticker would have an odd look w/ the concave like corners once peeled? Design is on par with the 80's. Backs at least are crammed full of stats for those number geeks.
I believe I ended up grabbed several of these packs and if they are still available I may grab a few more to feature in a future break...that is assuming there are people still reading the blog that would like to participate in a break.
