This logo, depicting an anchor and ship in stormy seas, was printed on Aitken’s shipping forms. As with any British colonist, Aitken would first need to brave the ocean before setting foot in America. One can imagine that this logo reflected both his personal experience as well as the overseas origin of his stock of books. In 1769, Aitken made a brief trip to America as a temporary sojourner, selling books and other goods he brought over from Scotland. Aitken returned home, but brought his family back with him in 1771 to establish permanent residency. On his trip, he shipped over enough supplies to start a business importing, binding, and printing books (see Sher, 532 ff.).
I replicate his 1777 New Testament, which was the first English New Testament Made in America & his 1782 Bible, aka The Bible of the Revolution, which was the first English Bible Made in America.
A version of this logo is found in the Marian S. Carson Collection, Library of Congress, and is printed in Richard B. Sher, The Enlightenment and the Book (University of Chicago, 2007), p. 533, fig. 8.4.
