How did we forget about ships for so long? Here are a couple more to give this thread a bump.
I wonder if Skinner's Dry Dock is still around in Baltimore.
And here's a RPPC of the USS West Virginia, mailed in Dec 1942. This shot had to have been taken more than a year earlier, as the West Virginia was one of the dreadnoughts that was sunk in shallow water during the attack on Pearl Harbor. She was refloated and repaired, but didn't return to service until 1944.
