A friend of mine bought a sealed copy last year from a collector, I don't know what he paid.
I have two copies, one I play and one is sealed as backup. I bought both when this LP was released in 1992. The cover on both my copies have a sticker on the shrink that reads:
Limited Edition 2 Album Vinyl Set Mastered Direct to Lacquer from Original Analog Tapes.
Both are marked "Made in England" I don't see anything in the art work that specifies how many pressings constitute "Limited Edition."
It's an extremely quiet pressing and very dynamic. I like Pink Floyd and Roger Waters, so this is an important LP for me personally. Funny thing is, when I bought these they cost $24.95 each and one of my friends thought I was crazy to spend so much money, especially for the back up copy.
