This collection primarily contains architectural renderings executed by Long in 1906 for a memorial issue of BUILDINGS magazine dedicated to New York architect Stanford White. These drawings represent White's most famous structures designed while he was a partner with McKim, Mead & White. Buildings depicted include Madison Square Garden, the New York Herald Building, and the Washington Memorial Arch, all in New York City, among others. Also included in this collection are miscellaneous architectural drawings by Long, Chester B. Price, and others, circa 1920s-1930s; and printed material.

Price's renderings, circa 1930s until his death in 1962, of designs by Warren and Wetmore, Benjamin Wistar Morris, III, and others; for the Hartford National Bank, Hartford, Conn. and the General Motors Building, New York City, designed by Shreve & Lamb; and other buildings. Also, eight photographs, undated, circa 1930s-1940s, showing the interior and exterior of Union Square Station, Toronto, Ontario (Price's relation to these is unclear).

This collection includes original and reprographic architectural drawings, black and white photographic prints, typescript specifications, and other papers relating to the architectural practice of Thomas W. Lamb, as well as his colleague and successor, John J. McNamara.
