This is tight and square - probably unread. 1" bend-trace at upper left corner of back cover and a hint of a bump-trace at upper right corner of front cover are the only flaws worth noting.

"Ivar Jorgensen" is a house-pseudonym which has been used by a number of authors including Ellison, Garrett, Silverberg. Paul W. Fairman may be the only author to use it for novels (not counting magazine serials...)

This is one of the hardest-to-find books with covers by Jeff Jones - especially in good condition.
