Joe Maddalena, Jon Mankuta and Fong Sam are on their way to an elite prop house in their own backyard. Abacus Costumes and Props gets props straight from films like Batman Returns, Camelot, Star Trek and The Patriot. Abacus is desperate to clear some space. Manager Steven Kirk wants the Profiles in History crew to take a look around and hopefully Joe can find some diamonds in the rough. An anonymous consigner sends Joe an Invisible Man poster, but he needs to make sure it is authentic since its provenance is questionable, so he heads over to Poster Mountain. Joe and Jon are in Philadelphia, PA in search of something for Joe's personal collection.
