Hey Dave, I'm totally talking out of my a**, but in my limited experience U.K. first pressings of that time frame on Atlantic had the red/purple labels, and subsequent pressings had the more common green/red. First pressings are just that, first from the first master tape, the first stampers, and call me FIRST in line to get one. Not sure about the Zep LPs, although I'd like to compare it to the pretty-damn-decent-but-maybe-a-shade-bright Classic reissue. Also, the vinyl might be a bit noisy, but the music is in dem grooves mon.
John,mon!? I havent heard that since high school when we were too cool!!! Thanks for the info,Anyone else??
David99. You got absolutely screwed! However, since you are my friend, so I am willing to go out on a limb and refund the money you paid for that first pressing. After all, what are friends for?

Just email me to work out the shipping details, and don't listen to anyone who tells you that it was a good deal ;~).
