Series I and II includes photographs and photostats of Weindorf's original work for the Public Service Commission. Drawings and models of subway tunnels, subway stations, subway line extensions, and other subway-related engineering issues can be found here. Many photos of drawings are mounted on thick brown scrapbook paper, with some items affixed to the verso.

Titles are transcribed, or, if in brackets, were assigned during processing. All sketches are by Weindorf unless otherwise noted.

Series III includes a number of posters and maps Weindorf designed for the Public Service Commission which may have been used as advertisements in subway cars and buses. They describe how to take the subway to various points of interest in New York City, such as the Cloisters, the Museum of Natural History, and the World's Fair grounds in Flushing, Queens. One poster details how to get to the "New York Municipal Airport Laguardia Field" by subway and bus. Weindorf designed many of the standard subway route maps used by the PSC in the 1930s and 1940s. Several of these maps appear here, including one with the routes of the IRT lines and another with those of the IND lines.

Titles are transcribed, or, if in brackets, were assigned during processing. The series is divided into two subseries: Maps; and Posters; thereunder, items are arranged by date, if known.

Series IV. contains newspaper and magazine clippings and articles. A series of articles about Weindorf in the Queens County Times from September 1973 to December 1974 details his life and reproduces some of his early cartoon and postcard drawings. Also included are three issues of the Interborough Bulletin, from 1913 to 1915. Several other clippings feature Weindorf's sketches of subway routes and stations.

Series V contains 110 photographs taken by the Public Service Commission between 1913 and 1938 to document the New York City subway construction. The photographs here are roughly grouped by subject and are mostly underground views. Weindorf may have used these photographs as visual sources for his drawings and models, especially those photographs of tunnels. Researchers should consult the Print Room's Subway Construction Photograph Collection (PR 069) for a description of these photographs.

Series VI includes what appear to be Weindorf's personal snapshots, as well as a chart showing public investment in transportation from 1860-1920. The snapshots date from 1903 and one shows children playing. A panoramic photograph of the west side of Manhattan island is also included in this series.

Series VII is comprised of both glass and film negatives. All but two are 8 x 10 inches. The two 11 x 14 negatives are both of subway route maps drawn by Weindorf in 1920. Most of the other negatives are images of Weindorf's models.

Negatives are organized by medium. All models are by Weindorf.
