Also comic book ads for other things like slot machines, a box that makes “real” money (by putting a blank piece of paper in it), and onion-flavored bubble gum (gross!).
Don’t forget the ads about “Charles Atlas” and also the little plastic army soldiers you could get in a small plastic treasure chest.
You don’t dream about male enhancement?
I bought sea monkeys one time. Of course I overfed them and they were all dead by the next morning. :-/
What happened was that many of the major publishers decided to get rid of the ads… and then jacked the prices up in order to compensate for the fact that they no longer had ad revenue to subsidize the cost of printing. $5 an issue is going rate these days, with special editions being $8 – $10.
Meanwhile, Alterna Comics is selling ad space like in the old days, and all individual floppies are $2 or less.
