Stanley Mouse, born Stanley George Miller (October 10, 1940), is an American artist best known for his psychedelic rock poster designs and album cover artwork during the 1960s and 1970s. He gained fame for his collaborations with fellow artist Alton Kelley, and together they created iconic posters for bands such as the Grateful Dead, Journey, and Steve Miller Band. Born in Detroit, Michigan, Mouse displayed a talent for drawing at a young age. Initially, he made a name for himself by creating hot rod-themed illustrations, heavily influenced by the work of Ed "Big Daddy" Roth. In the early 1960s, Mouse moved to San Francisco, where he met Alton Kelley. They became a part of the burgeoning counterculture movement, and their artwork for rock bands reflected the colorful, swirling, and surreal imagery that characterized the era. Mouse and Kelley's art became synonymous with the San Francisco psychedelic scene, and their work has had a lasting impact on graphic design and rock culture. Some of their most famous pieces include the Grateful Dead's "Skull and Roses" design, the "Zig-Zag Man," and the cover for Journey's album "Infinity." Mouse continues to create art, and his works remain influential and highly sought after by collectors. Stanley Mouse and Alton Kelley's partnership flourished as they became prominent figures in the San Francisco psychedelic scene, working alongside the likes of Wes Wilson and Victor Moscoso, who were also creating innovative posters and artwork. Together, they founded the Mouse Studios and the Monster Company, which served as their creative outlets. One of Mouse's most iconic designs, created with Kelley, is the Grateful Dead's "Skull and Roses" (also known as "Bertha"), which features a skull with a crown of roses. The design was inspired by a 19th-century illustration by Edmund Joseph Sullivan for an edition of "The Rubaiyat of Omar Khayyam." The image became synonymous with the Grateful Dead and remains a lasting symbol for the band. Mouse's artwork often featured intricate details, bold colors, and whimsical, otherworldly themes. He combined elements of Art Nouveau, Surrealism, and Pop Art in his designs. Mouse and Kelley were also among the first artists to use the split fountain technique in poster printing, which created a smooth gradient of colors. Beyond album covers and posters, Mouse has also designed concert backdrops, T-shirts, and various forms of merchandise. His work has been exhibited in galleries and museums around the world, including the Museum of Modern Art (MoMA) in New York, the Smithsonian Institution, and the Rock and Roll Hall of Fame. Although Alton Kelley passed away in 2008, Stanley Mouse continues to create art and is involved in various projects. His work remains a testament to the creativity and innovation of the counterculture movement and its impact on music and visual arts.
