Scarce German school geography, the first edition of which seems to have been published in 1753, and had the maps bound in individually, not on a single sheet. The latest date of a map on the sheet is 1785. The map of America shows California as an island; however, the double-hemisphere world map shows California as a peninsula. All editions are uncommon.
Condition Report: Boards rubbed, corners and spine ends worn, spine label not present (if there ever was one); some internal darkening, very good.
