The Navy's Bureau of Medicine and Surgery's historian's office holds a collection of newsletters and newspapers from various naval hospitals. U.S. Naval Hospital Aiea Heights had two issues and 2 fragments of an issue that are now online at the Medical Heritage Library. Here's the cartoons from them.
Robert Woodcock was one of the best of them and had two in the November 11, 1944 issue, and is featured in an article here.
Virgil Partch, aka VIP, was one of the best cartoonists and went on to a serious postwar career in cartooning. This is from December 15, 1945.
Al Santamauro (Nov. 11, 1943) and Bill Pietsch (Dec. 12, 1945) both seem to have disappeared from the cartooning world.
