An impossibly rare Atlantic Records test pressing of Led Zeppelin’s 1971 single “Misty Mountain Hop” (issued as the B-side of “Black Dog”) backed with a differently mastered version of the same song, dated December 2, 1971. This was likely produced so a choice could be made between the two different cuts by the mastering engineer, identified as versions 1 and 2.

This test pressing was made at the Specialty Records pressing plant in Olyphant, Pa.  The handwritten matrix numbers are:

(Side A): ST-A-22402-1  AT/GP
(Side B): ST-A-22398-11   AT/GP [with a yin/yang type sign, probably a Specialty Records logo]

In Near Mint condition.  One of only three Led Zeppelin test pressings we’ve offered.
