Philadelphia Lantern Slide Salon

Celebrate Archives Month Philly as we showcase glass lantern slides from six local special collections!
In the spirit of lantern exhibition culture, this salon will bring together unique and rarely-seen images presented in the context for which they were originally created. Viewers will join two scientists on their 1937 trip to Mexico to conduct fieldwork, witness the emergence of a new parish in 1919 North Philadelphia, experience the beginning days of the New Jersey Division of Parks and Forestry, get a glimpse of the inner-workings of famed stained glass artist Nicola D'Ascenzo and his studio, and so much more!
