The card in the top right is a design used by Modiano, an Italian company. I'm sure one of my packs has the middle-top one as its joker, but I couldn't find it when I looked through them just now. The bottom-left one would be good if it were in colour and didn't depict cards on the card itself. The second-left on the top line is one I've seen before but I don't have. The middle-bottom card is by Western Publishing (it says on it, "W.P. Co.,Racine, Wis."). I don't know anything about the rest.
Anyway, just so you don't feel this post was a total loss, here's something to gamify it and thereby make it fun. These are the backs of the above cards:
See if you can figure out which card has which back.
Answers tomorrow!
