The Culmination of the Historical Mapping of Manhattan.
Title, 5 leaves preliminary text, 186 pages of hand-colored lithographed maps (i.e., 93 double-page map sheets), 8 (of 26) pages of letterpress notes bound at rear.
Spielmann & Brush's atlas built on more than a century of cadastral mapping in Manhattan. Their project dovetailed with those of John Bute Holmes and R.D. Cooke in attempting to match modern street and plot configurations with historical land holdings. Real estate title was an important issue in the rapidly-expanding Manhattan market of the 1860s-1890s.
Prior to that High Ridge Books listed a disbound and incomplete copy (missing one map sheet) for $9,500 in 2006 (per OldMaps.com).
