Gregg Press: "First Printing, February 1978" hardcover (the paperback was in 1956 - as half of an Ace Double.) Cover by Jack Gaughan (same cover-art used for all six volumes of this set.) Condition is near-Fine in a VG+ to near-Fine dustjacket: the book is tight and square, with very mild or negligible age-tanning. No marks or writing - a very clean copy that looks unread. The SF club library put lots of stamps on - each front endpaper, title page & page 85, top & bottom page blocks, and 2 on the side page block. The DJ is in nice shape with no tears and very light wear; DJ protector had been taped to the dustjacket - so there are tape remnants on the back side of the DJ where it had been attached. DJ protecter was discarded because it showed some wear. DJ has a subtle vertical waviness on left side of front cover & right side of back cover (best seen in Scan #3.) My guess is that in 2 decades normal variance in humidity caused the dustjacket to expand in Summer(s), but the DJ-protector limited that expansion and so the gentle waviness resulted.

A note about the Gregg Press hardcover editions. Their print runs were low (typically 500 to 700?) and their quality is high: acid free paper, so age-tanning is negligible; the binding is sewn, and the boards are heavier than most. They will last much longer than the original, if there was one. Another seller dropped me a note to clarify something I thought was just an inconsistency: sometimes the credits page will state "First Printing" followed by a month and year - and sometimes not. Apparently they occasionally did another print run, and dropped the "First Printing" line on those. Most of the books they chose to reprint in hardcover were chosen for quality and popularity of the author - even when an earlier hardcover exists, the Gregg edition tends to be the preferred one.
