This is a block of four 12 Pfennig red definitive stamps from Nazi Germany, issued during the Third Reich. Featuring a profile portrait of Adolf Hitler, these stamps were part of the regular postage series introduced in 1941 under the Deutsches Reich regime. Such issues were widespread during WWII and served both domestic and occupied territory use. The design reflects strong propagandistic intent, symbolizing state authority. Blocks like this are historically significant but controversial due to the subject, often collected for WWII postal history context.
