This is an original 1948 black and white print ad for the Dopp-Kit Toilet Case by Charles Doppelt & Co. Inc. from Chicago.

Dopp Kit: The name derives from early 20th century leather craftsman Charles Doppelt, a German immigrant to the United States, who invented his toiletry case in 1919. The kits became widely known during the Second World War when they were issued to GIs. Doppelt's company was purchased by Samsonite in the early 1970s. Dopp kits were once a common gift given to adolescent males as they ascended from boyhood to adulthood. Although the term was originally a trademark, it appears to have at least mostly become generic, and the U.S. Patent and Trademark Office lists the trademark as abandoned.
