The Washington House Museum was selected by the US Postal Service as the site of the First Day Of Sale for its new ice cream-themed stamps. As the historic home of the ice cream sundae, the Washington House became its own post office for a day on June 30, 2016, issuing stamp memorabilia, hosting a presentation by the US Postal Service, canceling stamped mail and of course, serving ice cream sundaes.
