Continental Gummi Werke AG hand towel. It has some staining (I have made no attempt to clean it). Just a nice general towel. I am unsure of the exact age, I could see this being from the post war era, but the company was obviously doing stuff during the war. A lot of factories were modernized in the 1930's with a lot of mandatory improvements for workers, including wash rooms and dining facilities, so maybe it is war time.
