In those days I think the U.S. used tin as much as anyone else.....especially with tobaccos.......remembering disrespectfully "Prince Albert" kept in the can which I heard as a joke so many times. I do only remember chocolates coming in paper wraps or foil wraps....not often in a tin unless it was special Valentine's day candy. While working graveyard shifts the coffee that came in tins was mixed with the chocolate used for hot drinks to make a more potent caffeine mix for staying awake. That actually got to be a little too much caffeine for me so I would avoid that wanting to be able to get some daytime sleep. Oh and I read someplace that our simple tin cans became an important export to Japan where they began in post war years to re-use the tins for the making of many toys, odds, and ends that were often sold back to the U.S.----I remember these toy cap guns and toy cars made from thin recycled tins in my Xmas stockings that were often cheaply purchased. The toys never lasted very long before falling apart but were a good temporary thrill for many youngsters. Perhaps others can remember the red netting Xmas stocking filled with hard candy and cheap toys that could be bought at "Woolsworth" stores. We might get one of those at Xmas time often handed out by our local fire department as I remember or other civic groups.
