These R.C. Gorman Original Art Cards were produced by Saga Printing Company in Albuquerque, NM and sold in gift stores around the state during the until 1990's. The original lithograph is signed, though untitled, and is dated 1975. The inside of the card is blank. As printed on the back, Saga Printing promoted the cards as "Suitable for Framing" and "Original Art R. C. Gorman". I acquired these from an estate sale after the company went out of business.
The original art is printed on card stock 6-5/8" x 4-5/8". Each set of ten cards includes envelopes (5-1/4" x 7-1/4") and can be shipped to locations in the United States.
From Wikipedia: Rudolph Carl Gorman (July 26, 1931 – November 3, 2005) was a Native American artist of the Navajo Nation. Referred to as "the Picasso of American Indian artists" by The New York Times, his paintings are primarily of Native American women and characterized by fluid forms and vibrant colors, though he also worked in sculpture, ceramics, and stone lithography. He was also an avid lover of cuisine, authoring four cookbooks, (with accompanying drawings) called Nudes and Food.
