An extremely large c. 1907 map of New York City by Walker and Company. Walker's large scale folding map covers all of Manhattan, most of Brooklyn, Queens, and the Bronx, and parts of adjacent New Jersey. Only one subway line appears on the map and is highlighted in red. This is the IRT (Interborough Rapid Transit Company) running between several centers in the Bronx, through City Hall, to Atlantic Avenue, Brooklyn. The remaining public transport lines highlighted in green are part of the private above ground urban rail network in place prior to the full development of the centralized subway system. This unusual piece was a joint project between the Boston lithographer and map publisher George Walker (400 Newbury Street, Boston) and the New York firm of Wehman Brothers (158 Park Row, New York). Though undated we did discover a copyright registration for this map in 1907. The subway line terminates at Atlantic Avenue, the station for which was officially opened in the spring of 1908. It is however, not uncommon for cartographers to include projected improvements on their maps in order to keep them current beyond the initial publication date.
George H. Walker (January 4, 1852 - 19??) was a Boston based publisher of books, views, and maps active in the late 19th and early 20th centuries. Walker started his life as a dry goods merchant but developed an active interest in publishing during the early 1870s. Walker began publishing in 1878 when he partnered with an unknown New York Firm. Two years later, Walker brought the operation in house by partnering with his brother , Oscar W. Walker, in the opening of a lithography studio at 81 Milk Street, Boston. Shortly thereafter the firm expanded to new offices at 160 Tremont Street, Boston. The Walker brothers produced a large corpus of works, most of which focused on travel and tourism in New England. Walker also established the Walker-Gordon Milk Laboratory. This interesting investment was based on the premise that infant deaths could be avoided by providing higher quality milk. The company eventually became a great success, producing a high quality cow milk that closely resembled human breast milk. In the process the Walker-Gordon laboratory developed many of the dairy health standards that are still with us today.
Very good. Some minor wear and verso reinforcement along original fold lines.
