Postcard
A 1907 postcard credited to Carl Graebe, catalogued under science and technology history, and bearing a Musée du Louvre reproduction of Frans Hals's painting La Bohémienne. The picture is a black-and-white halftone of a smiling woman with dark curly hair, loosely painted in a white blouse, a designer might take its soft tonal shading and informal portrait pose as reference.
