These classic star atlases are in very good condition. Australis and Borealis are the 1976 Sky Pub Edition with folded pages and dark-red covers. The Eclipticalis is the 1958 Czechoslovakian Academy edition with the gray cover and full-size (not folded) pages. The complete set is $240 plus shipping.
Australis and Borealis were never used outside. The pages of Eclipicalis are only slightly wrinkled.
