WALDSEEMÜLLER, MARTIN. Oceani occidentalis seu terre nove tabula. [Strassburg: Johann Grüninger 1525]. Woodcut map, single sheet, 390 x 494 mm. (15 3/8 x 19½ in.), small light stain to outer blank margin, matted (unexamined out of mat). A reduced version of Waldseemüller's famous "Admiral's map," published in Johann Schott's 1513 edition of Ptolemy, the first printed map to represent the Americas. The present block first appeared in Laurent Fries's edition of Ptolemy, published in 1522. It includes more place names than the 1513 map and several references to the discoveries of Columbus, whose voyages are related on the verso. Burden 4; cf. Sabin 66481.
