Lucky Strike throw away razor

I believe the last photo is the patent of the throw away razor. It shows that the patent was on Sept. 6 1932.There is more pages on the patent describing the item by Burton Christmas of Pittsburgh Penna. I just came upon it. I thought it was a pack of matches. The sides fold down to provide the handle and there is a razor inside, used once and throw away. It is very old and I don't want to fold the brittle sides. It must have been ahead of its time. Any information on the article is appreciated.
