Led Zeppelin: Live At The Chicago Stadium 2lp 1975

Led Zeppelin - Live at the Chicago Stadium, Digger Productions, 2LP, 1975.
One of few Led Zep pieces that wasn t reissued over and over, at least not on vinyl.
The Chicago Stadium no longer exists, so kinda interesting for that.
The texture of the cover is also interesting as it appears that the entire cover graphics were stamped into the cardboard slightly so you can actually feel and see the indentation of all of it.
Unusual.
Also the only performance of Communication Breakdown from the 75 tour captured for posterity, according to one Zep expert.
