Geppi's Entertainment Museum is a private museum of American pop culture housed in a historic building at Camden Yards, covering the history of comics, toys, radio, television, and advertising memorabilia from the late 19th century to the present. Founded by comic book dealer Stephen Geppi, it contains over 10,000 artefacts and is one of the most comprehensive collections of pop culture ephemera in the country.
The museum is particularly strong on the Golden Age of comics (1938–1956) and on mid-20th century American consumer culture. Whether you find it fascinating or overwhelming depends on your tolerance for catalogued nostalgia, but the breadth and quality of the collection is undeniable. Located adjacent to Camden Yards, it is an easy add-on to a baseball visit.
