Thank you for the question! Your lithograph by William Pajaud (B. 1925) would sell at the gallery (retail) level for $400 to $600, which would be an appropriate value for insurance purposes assuming good condition. Generally, the artist's other lithographs from similarly sized editions sell for comparable prices.
