The next time you’re visiting the Railroad Museum of Pennsylvania, pull in for a stop to check out this cast iron builder's plate. This artifact was once displayed on a Pratt truss bridge built by the Union Bridge Co. for the Southern Pennsylvania Iron & Railway Co. This bridge is located on the Conococheague Creek between Marion, Pa and Williamson, Pa. ➡️ https://t.co/f9XnF8WMqg

Philadelphia's Plays and Players Theater may seem like an unlikely place for a moment in international history. Yet, a passerby may notice a small plaque inscribed in both English and Korean telling a much larger story that connects this neighborhood theater to Korea’s struggle for independence. ➡️ https://t.co/6CUntE9mwk

@PHMC honors all Veterans for their service. In this image preserved in the Pennsylvania State #Archives, a Civil War veteran finds his name on the Pennsylvania State Memorial at Gettysburg during the 50th Anniversary of the Battle of Gettysburg Commemoration, July 1913. #VeteransDay ➡️ https://t.co/Nl0rYpfUIZ

Philadelphia's Tun Tavern is best known as the birthplace of @USMC , but its legacy extends far beyond #military history. On Nov. 10, 1775, the Second Continental Congress passed a resolution establishing the Continental #Marines to serve as landing forces for the newly formed Continental #Navy (whose formation committee may have met at the Tun). ➡️ https://t.co/LN3BzRrh8t

The museum preserves this circa-1931 #voting machine.➡️ https://t.co/fEyY9J4L7s

It's nearly #Halloween 🎃 and we're sharing one the more spooktacular artifacts in our collection. However, we need to ask, is this probable 18th century “Witch bottle” archaeological evidence of witchcraft in Pennsylvania? ➡️ https://t.co/PM2VjwWazJ
