Publisher: I. Robbins & Son, Pittsburgh, PA. C.T. American Art Colored by Curt Teich Co., Chicago, Illinois.
I. Robbins & Sons of Pittsburgh, Penn. was a publisher of many postcards from 1911-1943 of which most were printed by Curt Teich.
Established in 1898, the Curt Teich Co. was best known for its wide range of advertising and postcards of North America. By the 1920s, it was producing so many postcards with borders that they became recognized as a type dubbed “White Border Cards,” creating an “era.” Later, Curt Teich’s innovations in this printing technique directly led to the production of what we now call “linens” by the early 1930s.
