hi fernando:
by any chance is the white rainbow box one of the titles you already had? (i'm thinking no.)

however, if you are considering selling it, drop me a note, off-forum.
that aside, yes, those are great snags indeed. and agree with drone on completely regarding finding such gems in that old...what are they called?...oh yes, record stores. i've written at great length (both here & elsewhere) about how the very fact that a record store is rapidly becoming a relic of the past speaks volumes about the gradual erosion of art, culture, and even civil commerce, in our society. an absolutely sad state of affairs.
i continue to frequent what shops exist in the metro new york city/new jersey area on a fairly regular basis (other music, generations, downtown music gallery, princeton record exchange, vintage vinyl - that's pretty much it), especially for the types of finds you came across. i certainly want the brick-and-mortars to survive - and my wallet does its part to ensure their survival, believe me!
