I have a collection of over 400 different band-aid tins. One of my favorites is a Johnson & Johnson tin that is only one-third the height of a normal band-aid tin. It looks like the vertical part of the tin was cut in thirds (complete with chopped off graphics), and the top and bottom applied to them, making three tins out of what was intended to be one. A friend of mine told me that J&J did that during war time to save money. It's a neat story, but I wonder if it is really true. If it is true, I haven't found the middle and bottom thirds used yet.
