This is the full set of The Dead's Europe '72 concert tour. 22 concerts on 73 CDs. Each slipcase contains all the CDs for an individual concert - most are 3-4 CDs, volume 7 is 1 CD and volume 17 is 2 CDs. Slipcases also include liner notes printed on the case. Full play list at: https://en.wikipedia.org/wiki/Europe_%2772:_The_Complete_Recordings

CDs are in excellent condition, but the cardboard slip-cases have some foxing and a few corner tears. 

NOTE: THESE ARE JUST THE CDs. This is NOT the Steamer Trunk Box Set + Bonus material.
