I've seen a few of these boxes of rubber bands come up occasionally. They are usually described as being from the 1930s. Not certain about the time period but they certainly look the part. I have found a later post war box with a different design from the same company so my opinion is these are probably 1940s at least. This one came with a good compliment of the original rubber bands with a noticeable amount of elasticity remaining but not at all useable. Great display to add to my other desk items.
