The "Recordings" and "Video" collections are of most interest to us. Why? Because they might contain
evidence of Django's concerts there on November 23 and November 24. If anyone could find out how
to retrieve anything from there, I'll be glad to help although I won't be able to travel to the U.S.
Photographs Collection
The Photograph Collection documents the visual history of Carnegie Hall. Images of the building (including photos from its 1891 construction) and the participants in events that have taken place on the three stages are part of this collection.
Posters Collection
The Posters Collection consists of promotional flyers, window cards, and large posters from a variety of Carnegie Hall events dating back to the 1890s. Some were displayed in cases on the exterior of the building; others would have been distributed by hand or by mail.
Programs Collection
The Programs Collection documents the performances that have taken place on all three stages of Carnegie Hall, and consists of printed concert programs from 1891 to the present. Some gaps exist in the collection, primarily for the two smaller auditoriums.
