Ace [1st printing] 1963 paperback (F-248.) Cover and title-page art by Jack Gaughan, 160 pages, 40 cent cover price. Condition is VG-: tight with mild lean; spine is flat/slightly-dished with wear to edge in bottom 1/2"; line next to spine (see scan); 2" finger-crease at right side of cover (see scan) and some damage/denting to page-edges beside it; light wear to back cover age tanning is mild and uniform (insides of covers slightly darker.)

Despite the list of minor faults, makes a good impression due to tightness and mildness of age-tanning (better than average for its vintage.)

Ray Cumming's Beyond the Stars, in its first book appearance. Original magazine appearance was in Argosy All-Story Magazine in 1928. Since I haven't read this - I'll have to quote from the inside blurb:

ONE OF THEIR ATOMS - OUR UNIVERSE! "The scene outside my window was a chaos: showers of white sparks were rushing at us. I tried to shout a warning, but instead I laughed with a touch of madness. I realized then that these sparks were really stars - and they were passing through us. I could see their luminous white points beaming within the vehicle as the stream flowed through. These stars were mere electrons and our vehicle comparatively was a puff of vapor."
