Serge Gay Jr. offers a love letter to resort city Palm Springs in his new show, “P.S. I Love You,” at Voss Gallery. Bathed in sunshine and a Mid-Century Modern sensibility, the works are a stirring blend of acrylics and graphite. “Popularized in the 1930s as a fashionable getaway for the Hollywood elite, the human-built utopia has become a haven for creatives lured to the vast desert as an artistic escape and source for inspiration,” the gallery says. The show, which begins on Oct. 11, runs through Nov. 2 at the San Francisco space.
