That sounds very thrilling! I´d be really happy to see it! Today there is still a lot of research done on German Comics history but the cartoonists who were not doing straight comics are mostly ignored. That goes double for the part that they played in Nazi-Germany. A lot of cartoonists like Ferdinand Barlog and Will Halle were working successfully from the 30s to the 50s. The one cartoonist that influenced those two the most, was Berlin cartoonist Paul Simmel. He committed suicide in 1933.
If you would scan the postcard I´d like to post it alongside a new Will Halle post. If possible, please make a high-resolution scan.
Thanks a lot1
