Hi Geri,
I have a BAND-AID® Brand Adhesive Bandage tin that's very similar right here in front of me! The original BAND-AID® Brand boxes in 1921 were cardboard, and they were produced in metal after that. Initially the adhesive bandages were not pre-cut, as they are today, and we printed instructions on how to cut the width needed and apply it on the inside cover. Because BAND-AID® Brand Adhesive Bandages were the first pre-made commercial dressings for small wounds that consumers could apply themselves, it was a very new concept for consumers, so we included the visual instructions on how to use them. As soon as Johnson & Johnson built machinery to make them pre-cut, they were no longer in square containers and were in the more familiar-shaped tins. So you have a collectible from the early days of the product! I don't know what the actual worth of your tin is, but you can check online auction sites to compare, or check in with a local antiques dealer.
Regards,
Margaret
