This second printing has a great cover by Dean Ellis - part of a matching set from this period. In my opinion, this is the best looking edition for this book.

Ballantine Books (#01663) 2nd printing July 1969 paperback. Cover by Dean Ellis, 154 pages, 75 cent cover price. Condition is VG+: tight and almost square with flat spine; age tanning is mild and uniform (average to decent for its age, and no darkening inside covers.) Light overall wear - mainly as a checkmark in pen below title (almost lost in the art), and rubbing/wear to back cover (see scans.) A few numbers/letters written at top right of first inside page - no stamps, marks or other writing.

ALTERNATING CURRENTS (1956) - an early collection of stories by Frederik Pohl. This was the first appearance in a Pohl collection for any of this set. Several of these appear in later collections, including 2 stories in The Best of Frederik Pohl - but 3 have not been re-collected.
