Trademark of Quality (abbreviated TMOQ or TMQ) was a bootleg record label based in Los Angeles, California, and was established in 1970 by "Dub" Taylor and Ken Douglas.
Another 9 titles followed before they 1970 created the "farm pig" logo and the TMQ label was fact then they began fastening round fluorescent stickers on the outside of their rubber-stamped jackets which read 'Trade Mark Of Quality,' and bore the profile of a farm pig.
Over time, custom pig labels were added along with xerox insert covers.
They were made with the same stamping plates, similar labels, stickers, and inserts.
Dub went until 1974 and briefly returned in 1976 and 1977 with a small series of deluxe-covered titles before dropping out entirely.
