Stereographing America: A 3 – D History Using Stereocards

March 1st, 2022 until January 30, 2023

Join Pennypacker Mills in discovering the evolution of 3-D devices – from the original Wheatstone stereoscope, fly past the Brewster stereoscopic design, and move on to the popular Holmes hand-held model – to learn how modern 3-D technologies have become household commodities! The exhibit will feature stereoscopes and numerous stereocards from the collection of Pennypacker Mills. All visitors will be able to experience the 3-D effects first-hand when viewing the stereocards by using a lorgnette provided upon entering the galleries. We invite visitors to experience the ‘magical illusion’ in person!

The exhibit is located in the second floor galleries and is included on all guided tours.

All ages are welcome to visit the free exhibition.
