WWII 1944 Trench Art Italy ROMA 44 Ring Sweetheart

Aluminum ring with flat face, engraved with aqueducts in background and ROMA 44 below what looks to be a river, and what could be two stylized submarines with telescopes up (maybe not).
It seems to be a large ring and has glue residue from tape on the back, probably to make it fit a smaller finger.
1 inch front to back, the inside diameter is about 3/4 inch.
