 Trade Mark of Quality was established in 1970 by "Dub" Taylor and Ken Douglas.They were quality-conscious perfectionists who pressed all their albums on coloured, virgin vinyl, and possibly the first bootleggers to start producing printed picture covers, and later colour picture covers, rather than paper inserts.Taylor and Douglas had released several albums under different names before settling on "Trade Mark Of Quality" in 1969, the first being "Great White Wonder" by Bob Dylan.
