From the best we can tell, this is a variation of the Original run of 1972 pressings as it contains the 'CANADIAN LTD' in the matrix runout and identical catalogue numbers on the labels. 
Sleeve has light corner wear and the vinyl is closer to NM, with only the faintest surface mark on Side A that completely inaudible.
The sound is incredible and contains the warmth and punch you'd expect from the H.C. pressings of this era.
