Most of the topics identified in this subseries relate generally or tangentially to Kimball's studies in art, architecture and early American history. The unidentified photograph of a cat and dog is an exception. While clippings and photographs comprise most of the documentation, there are also a series of oversize photostats Kimball made of the architectural drawings of John McComb Jr., the architect who designed New York City's Old City Hall of 1811. Correspondence and a few catalogues are also included, as well as a special issue of Vanity Fair devoted to America's Sesquicentennial.
