Comic book vending machine - 1967

Once upon a time, you could get your favorite comic books from a machine!
It worked like a snack machine, putting a row of comics on a corkscrew instead of Twinkies.
There was one book in view at the top/front of each of the ten stacks and if you didn't see one you liked, you'd just come back later and there would be other ones showing.
You'd put a dime in one side and two pennies in the other side of a thing like the coin slots on washers and dryers.
Then you'd push it in and pull it back out, turning the corkscrew so that a single comic book would drop off and slide down to a little slot at the base of the unit.
In July of 1966, I saw one for the first time and bought Daredevil #32 and Avengers #44. I still have them!
Sorry to say the machines aren't around any more.
They were re-tooled in 1969 when comics raised their prices from 12¢ to 15¢ and again in 1971 when the price went up to 20¢.
After that, comic prices continued to skyrocket and changed faster than the machines could be retooled, so they were retired instead.
