Carl Griepenburg (December 25, 1906–1981) was an American painter whose career spanned more than five decades, from the golden age of hand-painted movie posters to the flourishing plein-air and street art movements of Florida and San Francisco. He began his artistic career in the 1920s designing theatrical and movie posters (the films of Marlene Dietrich, Carole Lombard, Claudette Colbert, etc…) throughout Iowa and South Dakota, working during an era when large-scale posters were painted by hand using airbrushes, brushes, and opaque paints to create dramatic, highly visible images. Before photographic reproduction became commonplace, these artists combined technical precision with bold color, typography, and composition to produce striking images that were themselves works of art. This demanding commercial training gave Griepenburg a confident command of color, draftsmanship, and visual impact that can be seen in his bold images of San Francisco.
By the 1950s and 1960s, Griepenburg had established himself as a respected painter in Florida, earning the affectionate nickname "The Florida Painter." For more than a decade he also taught at the Boca Raton Museum of Art, where he shared his enthusiasm for painting with a new generation of artists. In the 1960s he relocated to San Francisco, becoming one of the city's original street artists and supporting himself through the sale of his paintings while working outdoors. He eventually settled in Point Richmond, where his evocative landscapes and coastal scenes earned him local recognition as the "Point Artist of Point Richmond."
