The collection includes 1134 images (photographs and postcards, with some duplicates) of approximately 60 buildings, including some earlier photographs, plans, and renderings that Morris copied to add context to her own contemporary photographs. Of properties with identified architects, the great majority were designed by Alexander Jackson Davis, with a few examples of the work of Richard Upjohn, James Renwick, and several other lesser-known architects. Major sites depicted include Lyndhurst, Tarrytown, N.Y.; Fonthill Castle, Bronx, N.Y.; Lovat, Hastings-on-Hudson, N.Y.; Hurst-Pierrepont, Garrison, N.Y.; Belvoir, Yonkers, N.Y.; Beechwood, Yonkers, N.Y.; Mount Ida, Troy, N.Y., Llewellyn Park, Orange, N.J.; and Malbone, Newport, R.I. Some 18th-century buildings, and one 17th-century building (the Christopher Billop House, near Tottenville, Staten Island, built circa 1699), are also depicted.
