An artist about whom very little is known, it is believed that Wentworth died around 1960. He worked in the San Francisco area in the 1950s, but spent most of his life in Southern California. A legend grew that his P.M. moniker derived from his evening work as a night watchman at a naval facility, until a signature discovered on one his paintings finally revealed that his real name was “Perley.”
Wentworth expressed his interest in the stars, planets, and worlds beyond our own in his drawings, many of which allude to Christian theology. To confirm that his concerns were not of this world, Wentworth wrote the word “imagination” on many of his works. While based on Biblical stories, his interplanetary interpretations extend beyond traditional Christian iconography.
