Dedicated record collector since 1981; partial towards label variants either from or typeset by Columbia Records' pressing plants in Bridgeport, CT (pre-1964) and Pitman, NJ (1964-86). Also prefer East Coast pressings in general, from RCA Custom in Rockaway, NJ (1954-73), Decca/MCA in Gloversville, NY, Capitol in Scranton, PA, etc.
{Images #2681823 & 2681825} would have been pressed after Bill Cosby bailed out of the Tetragrammaton partnership. Both that and {Images #982703 & 982704} had label typesetting from Columbia Pitman.
Sounds like it's contingent on which pressing plant turned out which copy that had which label. {Images #1897117 & 1897118} was pressed by All Disc in Roselle, NJ, with Progressive Label & Litho type - and they were apparently the ones that turned out the World Pacific Jazz copies. Sounds like there was a blurring of what was what, once Pacific Jazz turned into World Pacific Jazz after the label designs were revamped to mention Liberty/UA, Inc., in the rim print.
