Penny slot at top. Soda retrieval at lower right.
Paper chute on reverse, for tossing tiny paper sodas down to the customer. Soda stock in pockets. Penny pocket at upper left.
I made this paper soda machine when I was a kid, to vend tiny paper “cans” of cola for 1 cent each. Drop a penny in the slot at the top, and your beverage would appear at the bottom of the chute! See photos to see the chute mechanism on the back side.
