This was found in a military collection of early army air corp materials at an estate sale. I was told it was a wall insignia from a unit in the 20's-30's Military office/unit. I originally thought it was cast aluminum but it is actually silver painted porcelain.
It's in the original frame which has marks and signs of repair. There have been some touch ups to the paint over its life but presents well.
I re-taped the back as it was loose, and didn't want it damaged. It's approx 25x12 and as you can see In the photos it's dimensional.Very cool piece for the collector.
