Collection consists of five binders of photographs of different regional residential architectural styles, one unpublished manuscript entitled "The Architecture of Old Cuba" and some notes on Post Colonial architecture. The binders and the manuscript consist primarily of black and white photographs of architectural structures, which have been adhered to sheets of paper by Major. The binders have photographs primarily of residential structures throughout the United States. A note accompanying the collection indicates that the majority of the photographs in the binders were used to illustrate "The Domestic Architecture of the Early American Republic." The two binders titled "North Atlantic Seaboard" (parts I & II) feature towns in Maine, New York, Vermont, Massachusetts, Connecticut, Pennsylvania, New Jersey, Delaware, and Maryland. The binder "South Atlantic Seaboard" focuses on Virginia, Washington D.C., North Carolina and South Carolina, Georgia, and Florida. "Old Northwest" covers Ohio, Illinois and Michigan, and the "Old Southwest" binder covers Georgia, Louisiana, Kentucky, Alabama, and Mississippi. The manuscript "The Architecture of Old Cuba" covers many aspects of Cuban architecture, including the history of its development from the 16th century through the 19th and the functions of major components such as windows, grills, doorways, arcades, and patios. Howard Major does not seem to have taken the majority of the photos; most of the photographs of Cuba can be attributed to the American Photo Studios in Havana, Cuba. Within the binders he identifies the photographer by last name with a note. Within the manuscript, there are some pages of text interspersed within the photograph pages. His perspectives on each image are recorded in the notations at the bottom of each page.
