The South Street Seaport Museum’s newest exhibition juxtaposes the First Class and Third Class passengers aboard ocean liners of the early 20th century and the differences in their transatlantic travel experiences. The exhibit will feature artifacts from the museum’s permanent collection, including ocean liner memorabilia, ceramics, travel trunks from both classes and ship models. Film screenings will show footage of life aboard these ocean liners as well as the immigrants that worked in the New York Harbor. Not be missed: a view of master woodcarver Deborah Mills’ ongoing project in the museum’s Maritime Craft Center as she recreates a piece of wood paneling that was once a part of the Smoking Room of the RMS Mauretania. All ages.
