DESCRIPTION: SOLD
Fine and quite scarce antique chart of the Harbor of Hyannis, Massachusetts published in 1850 by the U.S. Coast Survey on heavy paper. Contains a list of dangers, a tide table, sailing directions, and two long elevation views of the East and West entrances to Hyannis Harbor as seen from sea. Key features include: Bishop and Clerks Rocks, Point Gammon, Gazette Rock, Gallatin Rocks, Senator Shoal, and Harbor Bluff. With numerous depth soundings and fine topographical detail on the coastal margins. Electrotype copy no. 2 by Mathiot.
Hyannis is the largest of seven villages comprising the town of Barnstable on Cape Cod. The town is best known as the presidential retreat for the Kennedy clan who spent any available downtime at the family compound in Hyannis Port.
This is a scarce, separately issued, rolled nautical chart of Hyannis, MA. on heavy paper, not the more common folded version on thin, trimmed paper that was issued with other charts in an annual report to Congress from the Coast Survey.
Under magnification fine detail is visible assuring the buyer of it's origin as an copperplate (electrotype) engraving. This chart was printed by the U.S. Coast Survey in 1850 from an electrotype copy of the original hand-engraved copper plate, a process the U.S. Coast Survey newly adopted in mid-century and that resulted in incredibly fine detail without the work of re-engraving after every few hundred copies.
As a soft medium, copper plates could only withstand print runs of perhaps 200 copies before the plates wore down. To enable larger print runs, a mold of the original plate was created in wax or another soft medium. Then, using an electro-chemical process ( electrotyping ), the mold was coated with a metal layer, typically copper. Printers were then able to produce output from the new electrotype copper copy, while preserving the original.
