The Rings of Saturn; The Moons of Jupiter (The Third Isaac Asimov Double) (Lucky Starr series)

Frist thus.  A copy of the scarce double edition of the final two parts of Asimov's Lucky Starr series, containing both The Rings of Saturn (first published in 1958 under the title Lucky Starr and the Rings of Saturn) and The Moons of Jupiter (first published in 1957 under the title Lucky Starr and the Moons of Jupiter).  286pp.  Mid blue cloth-covered boards, gilt lettering on spine.  Blue endpapers.  8vo.  Cloth just a little rounded at corners and spine ends.  There's a small area two which liquid paper has been applied (perhaps covering a previous owner's name) on the front free endpaper and the pages are moderately tanned, especially in margins, else novel is neat, clean and tight).  In its original dust wrapper, not price clipped, a little faded, rubbed around edges with some delamination creating minor roughness, partially minorly bumped around edges.  Dust jacket now protected in an archival-quality Mylar sleeve, fitted without the use of tape or adhesives.
