Trade Mark of Quality (TMOQ) was a pioneering bootleg record label from Los Angeles that rose to notoriety in the late 1960s and early ’70s for releasing high-quality, unauthorized live recordings and studio outtakes from rock legends like Bob Dylan, Led Zeppelin, and Pink Floyd. Known for its distinctive pig logo and use of colored vinyl and printed sleeves, TMOQ elevated bootlegging into a collector’s art form, blending countercultural rebellion with audiophile sensibilities. Founded by Dub Taylor and Ken Douglas, the label helped define the underground music scene, offering fans raw, unfiltered access to performances that official releases often ignored.
