Hello to the 348th - I found some wonderful soldier sketches from USO shows in Germany by Mimi Korach Lesser. There are quite a few for the 348th Engineer Combat Battalion from August 1945 from Eberbach, Neckargmund, Burstadt, & Walldurn. They are posted on the Veterans History Project site.
I spotted ones for the 348th starting at the bottom of page 51, page 52, page 53 (could be others):
