Vintage WWII Black Leather Seaman's Identification Wallet

This is a World War II era U.S. Merchant Seaman Identification Wallet. These items were used by civilian merchant mariners to hold their work history and identity documents during the war effort.   Issued by the U.S. Department of Commerce in Washington D.C.   Typically made of black leather with embossed lettering and a snap closure.   Merchant mariners were civilians, but the U.S. government could use them for defense during conflicts.   They had a higher mortality rate than any of the military services during WWII.
