LONG message not re-posted...! Now, as I recall, the original post for this thread came from a chap who was collecting (both in actuality and as digital images) information on all (?!) the Wisconsin-based record labels of the "microgroove era"...?! That post made NO mention of 78's and/or their labels and sleeves (rather a shame given the abundant history involved with 78's recorded/pressed for Paramount 192?-1932)...IIRC, the collector who originated the thread was much more concerned with the rock bands and their limited-quantity record issues...?! There are good books (I own a couple) on the evolution of Victor and Columbia 78 labels (but admittedly not sleeves); I also did a detailed article on the evolution of the various Grey-Gull-related makes and their labels, for the now-defunct New Amberola Graphic (BTW...does anyone know to what extent NAG back issues are available...and if yes, HOW does one acquire them?!) publication. Above and beyond those, I wot not of other 78-label writings. However, as I note above, the thread started out referring to microgroove ephemera...and made NO mention of 78's...?! Steven C. Barr
