Orville Ewing billed himself as an "artist from the Old West". He traveled the United States with his covered wagon/trailer and menagerie for about 30 years starting in 1938.
He sold many different postcards of himself over the years. These are from the 1950s. I have five different postcards of him, and I know there are a lot more. The text on the front of the first card was used on many of his postcards, and there seems to be very little other information about him available. Have traveled from the Atlantic to Pacific Coasts and from Canada to Mexico — at San Francisco World's Fair in 1939, and at the New York World's Fair in 1940. — I gave up oil painting becasus the paint affected my health, and started pencil sketching in 1938.
