Richard,
Over 400 tins -- that's a fabulous collection! The BAND-AID® Brand Adhesive Bandages tin with chopped off graphics that you described sounds interesting, but doesn't sound like something that Johnson & Johnson would have produced, since we were always very careful about properly displaying the product's complete name and graphics on the packaging. Throughout the BAND-AID® Brand's history, the tins have come in a variety of shapes and sizes. The first ones starting in 1921 were flat and square, and later some were round like canisters. During World War II Johnson & Johnson didn't cut down existing tins but in 1943 went temporarily to cardboard packaging for BAND-AID® Brand Adhesive Bandages. This was due to shortages of material to make the tins because of the war effort. If you send me a picture of the tin, I would be happy to take a look at it. You can find a link to email me on the blog's "About the Author" page.
