Posting this on behalf of a friend, apparently a U.S. Navy Air Station-Lakehurst armband for the ground crew of Hindenburg. As can be see, it's dated 1937, the year of the Hindenburg fire & crash.
This is certainly not my area of collecting and have not been able to find another example of this armband. This website below what I was able to find. Attached here is a button shown on the website which appears to be a match to the armband.
Any and all comments appreciated. An obscure piece, but if anyone can manage an opinion on $ value, that would be great as the intention is to sell it.
