During the 1950s, Sam Savitt frequently illustrated the covers of iconic western-themed comic books. Little of the original artwork used for those covers survives. This is one of the rare examples. The right half of this watercolor, whose entire image measures 13 by 19 inches, would have been the front cover. (That’s why the signature appears in the center. ) The left side of the painting was the back cover. Price: $2,125.
