This remarkable 32" x 20" antique two-sided map offers a dual historical perspective on two critical East Coast cities: one side features a detailed plan of Washington D.C. (likely "Wa" referring to the District, not a state) and surrounding Maryland areas, while the other side presents a comprehensive map of Philadelphia (labeled "Philadelphia"), potentially with some parts of Delaware implied. Published by G.W. Gray & Son, a prominent Philadelphia-based firm established in the late 1860s, this map is a testament to their renowned cartographic quality. Celebrated for producing one of the most successful atlases ("Gray's National Atlas") and for being "one of the last to employ hand coloring on maps," this piece likely dates from the 1870s. It provides invaluable insights into the urban development and layout of these major American cities during a pivotal era of growth. An exceptional find for collectors of urban historical maps, East Coast Americana enthusiasts, or as a truly distinctive decorative piece.
