The map is large and comprehensive, extending from the Babuyan Islands to the Sulu Archipelago, encompassing most of the modern day Philippines with the exception of Palawan. Cartographically it is derived from the 1870 work of Claudio Montero y Gay. The map exhibits limited depth soundings throughout, but particularly between major island groups. American telegraphic cables, both extent and projected, are highlighted in red, while British lines appear in blue.
Andrew B. Graham (1845 — September 9, 1909) was an American lithographer active in Washington, D.C. in late 19th and early 20th century. Graham was born in Washington D.C., the son of a lithographer and engraver. After college, he joined the U.S. Coast Survey, where he was a draftsman until 1889. He retired from the Coast Survey to take over management of his father’s lithography firm. The firm, Andrew B. Graham Company, was one of several that thrived on lucrative government publication contracts. Graham died of ‘brain fever’ in his Washington D. C. residence on September 9 of 1909. Some of his work was republished posthumously until about 1917.
