3EP Ltd. was founded by Moo (Mary Margaret) Anderson, Joseph Goldyne, and Paula Kirkeby in 1978 in Palo Alto, California. The print publisher worked with over 20 artists to produce fine art prints and monotypes and operated until 1984.
Harry W. and Mary Margaret Anderson, respectively known as Hunk and Moo, are avid art collectors with one of the largest private art collections of 20th Century American Art. Moo has a special interest in works of art on paper and prints. Moo and Paula Kirkeby, director of Smith Anderson Gallery in Palo Alto, along with San Francisco artist Joseph Goldyne formed 3EP Ltd. In addition to sales, the mission of 3EP Ltd. was to encourage experimentation with the monoprint. Anderson and Kirkeby commissioned a custom-built Takach-Garfield press for their facilities and invited artists to work with the monotype technique and printmaking, techniques that were initially unfamiliar to many of the artists who worked with 3EP Ltd. Artists invited to work at 3EP include Gordon Cook, Claire Falkenstein, Joe Fay, Sam Francis, David Gilhooly, Frank Lobdell, Ed Moses, Nathan Oliviera, Jay and Matt Phillips, and many others. 3EP Ltd. closed in 1984.
