FAO Schwarz is the oldest toy store in the United States, first opening its doors in 1862 in Baltimore before moving to New York City, where it has moved between several locations since 1870. The dance-on piano, made famous by the 1988 Tom Hanks’ film Big, brought national attention to the brand.
FAO Schwarz was founded in 1862 in Baltimore under the name "Toy Bazaar" by German immigrant Frederick August Otto Schwarz.
In 1870, Schwarz opened a New York City location known as the "Schwarz Toy Bazaar" at 765 Broadway, which moved to 42 E. 14th Street in Union Square in 1880 and operated at that location until April 28, 1897, when it took over two vacant store locations at 39 and 41 W. 23rd Street. By then, The New York Times described Schwarz as "the largest dealer in toys in this city.
FAO Schwarz is known for its large assortment of plush animals and the Piano Dance Mat, a smaller replica of The Walking Piano featured in the Tom Hanks film Big. FAO Schwarz also features limited-quantity luxury items including a drivable, child size Mercedes Benz encrusted with over 40,000 Swarovski crystals and valued at $25,000.
In addition to its own line of products, FAO Schwarz carries brands including Steiff, the world's oldest and best-known German designer of stuffed animals, Melissa & Doug, a leading designer and manufacturer of educational toys, and Build-A-Bear Workshop, a Make-Your-Own experience featuring a selection of exclusive FAO Schwarz furry friends and accessories, among other in-store retail partners.
