Hammett’s Planisphere, Showing the Principal Stars Visible for Every Hour in the Year, From Lat 40° N.

1900. Cambridge, Boston, Newark: J. L. Hammett Company, Educational Supplies, n.d. [c.1900-15].

Functioning planisphere consisting of a 10” circular paper-covered board bearing a map of the heavens and a calendar marked in days, months, hours, degrees, and astrological star signs, the circle positioned to rotate within an elaborately gilt-stamped pointer-frame with explanations for use printed on the reverse. In fine condition with the small bookseller ticket of Paul Elder & Co. San Francisco on the reverse, in the original very worn printed paper envelope.

§ An attractive and fully functioning planisphere. Stamped “Made in Great Britain”, the Paul Elder ticket suggests it came to San Francisco almost immediately, and the lack of wear suggests it was practically untouched once it arrived. Item #110518

Price: $250.00
