This grouping showcases beautifully illustrated charity stamps from the Für die Jugend (“For the Youth”) series issued by Deutsche Bundespost and Deutsche Bundespost Berlin. The 1967 issues depict small native mammals: the Weasel (Wiesel) on a green background and the Hamster on red, both designed with a clean modernist style typical of the 1960s. The 1969 issue, showing the Kaltblut (a heavy draft horse), continues the theme of promoting youth and wildlife awareness. Each denomination carries an added semi-postal surcharge benefitting youth welfare programs. These stamps remain highly collectible for their crisp animal artwork and social purpose.
