This commemorative 80 Rappen stamp from Liechtenstein honors Carl Lindenberg (1850–1928), a prominent German jurist, philanthropist, and pioneer of organized philately. Issued in 1950, it belongs to the “Philatelic Personalities” series, celebrating notable contributors to the world of stamp collecting.

The finely engraved portrait, designed by A. Pilch and engraved by A. Nefe, depicts Lindenberg with meticulous detail, emphasizing his dignified expression and scholarly bearing. Lindenberg was instrumental in establishing early philatelic institutions in Germany and served as honorary president of the Berliner Philatelisten-Klub.

This issue holds particular significance for philatelists as one of the earliest tributes to a stamp collector on a postage stamp itself — symbolizing the growing recognition of philately as a cultural and scholarly pursuit.
