I googled it for you. From Popsike:
How to spot a reissue. This record was reissued in 1977 and it’s pretty easy to spot the reissues. There is a line of text saying it’s a reissue below the picture on the back of the jacket. The line of type running vertically on the right side of the jacket is down the spine of the reissue. The faces on the front cover, which are grey halftone screens, are high contrast black on the reissue, and finally, the reissue appears to be one continuous track, while the originals have songs banded apart like a normal LP.
