The sender information on this envelope indicates that it was issued by a company named Excelsior Dry Plate Co., based in Rockford, Illinois. Although we do not possess definitive records about the company, it is highly likely that it was founded sometime between 1880 and 1890.

Excelsior Dry Plate Co. specialized in the production of dry photographic plates, also known as dry plates. These plates represent a photographic technology that was developed in the late 1870s and achieved significant commercial success especially during the 1880s.

Archival Significance: This envelope documents the Excelsior Dry Plate Co., a small but significant manufacturer operating in Rockford, Illinois, during the crucial transition period from wet collodion to dry plate technology in the 1880s. Dry plates, which could be factory-coated and stored for later use, revolutionized photography by making it more portable and accessible. Companies like Excelsior played a vital role in this transformation, serving regional markets and contributing to the commercial infrastructure that supported both professional and amateur photographers. While larger manufacturers like Eastman dominated the narrative, regional producers like Excelsior were essential to the widespread adoption of dry plate technology across America. This item is a valuable primary source for understanding the decentralized nature of early photographic manufacturing and the commercial networks that supported photography's expansion in the late 19th century.
