I love those little stickers with name and adress on cover of LPs. I rarely remove them, exept if thaty are on front cover. I recently bought record from Holland : various dealer, but same collector, that used to wirte his name (E.T. Lettinga) and add some sentences : heres' one, on the back of The Happnins (New Jazz 8246) :
"Rockers forbidden, except whenever this item leaves the shelf and except for Granville's spanish cohorts featured at ray Bryant's feelings" (Gnraville Rocker is the drummer of the session, his name is underlined on the credits)
I also have many NM Blue Note from a mysterious "MD" stamped on back...
This topic proves the evolution of the appreciation of records : in their times they were not collectors item, just someones personal objetcs. We collectors would like to find them immaculate, in other words, out of history and society, with no age.
