I grew up with Wacky Packages and was glad to see them make a comeback. I was also born in the same year these stickers came out, so I guess I should be especially nostalgic for them. I used to collect these stickers and put them in an ordered poster I made on my room door when I was a kid.
I don't know if they'll come with a stale piece of rock hard bubble gum also, but most kids didn't buy the cards for the gum. I sure didn't.
Here is the cover of New York Magazine in 1973 for them.
