The best accoutrement of the 12-inch LP was its cover. On its big field, photographers and designers produced masterpieces of commercial artwork, especially for jazz albums. In New York in the 1950s, Blue Note Records featured Francis Wolff's intense performance photography, the perfect visual complement to the dark heat of bebop and hard bop. In California, the music was cooler and sunnier. As LP-cover-sized page upon page of this splendid culling--mostly from the Pacific Jazz, Contemporary, and Fantasy catalogs--shows, William Claxton and his associates forged a relaxed, humorous visual style to match California jazz's suavity. The West Coasters used more posed, even gimmicky, portrait photos than their New York counterparts used; and they reveled in buxom blondes, cartoons, and visual jokes when they got tired of portraiture. They created a uniform look by restricting the palette of any single cover and by favoring sans serif and typewriter typefaces. To this day, their work, however dated, is clean and lighthearted, educing the smile to go with the tapping foot that the music provokes.
