Factory Additions was the publishing business Andy Warhol created in 1967 in New York City. The name is a play on the term “Editions,” which is the word one would expect to he in the title. Warhol had a team of printers and designers who helped him constantly produce new art, with the Factory pumping out some of Warhol’s most famous print series. Marilyn Monroe, Campbell’s Soup I and II, Flowers, and Cow were all published by Factory Additions.
