Technically marshmallows aren't a candy, but I couldn't resist the 20's deco ad. O.T. Stacy was part of a marshmallow boom in Rochester NY back in the teens and the company presisted until the Great Depression took the air out of its stocks and its products. I did some digging and the one thing I was able to find on O.T. Stacy as a little lawsuit for violating FDA standards by adulterating their products with silica. Not exactly the kind of trick you want in your treat bag.
