Last weekend I was in a Reserve Center near Toledo. Anyone who's been in an HQ building has seen the display cases of old trophies. This place was no different and this trophy caught my eye for obvious reasons.
Wikipedia says the XX Corps "was subsequently active as part of the Regular Army from 1957 until 1970 at Fort Hayes, Ohio." Fort Hayes in Columbus and my guess is a Reserve unit moved to Toledo at some point and took this with them, not knowing what it was. At 40 years old, it's not likely the Lieutenant is still in uniform, but it would be cool to track them down and let them know where their trophy is.
