The Regional History Center's postcard collection contains over 2,500 individual cards and provides a unique source for photographic and artistic documentation of people, places and events, the majority during the 1900-1940 period. A majority of the cards in this collection came from four manuscript collections held by the Center: W.W. Embree (RC 2); Sabin-Van Arsdale (RC 32); Kavadas (RC 50); Hall Family (RC 117)., Although most of the cards depict scenes or events from the Northern Illinois region, other states and foreign countries are also represented in the collection. The main body of the collection is arranged by geographic place name, and the remainder arranged by subject. In addition there are oversize postcards and packets which are housed separately. Completing the collection is a box of non-postcard materials of related interest including advertisements, blotters, holiday cards, and Bible verses and proverbs.
