Come one, come all for a very special opportunity to "leave your mark on history" by writing your signature on a 22-foot steel support beam, one of three being installed to strengthen the framing and increase the floor loads as part of basement-to-attic renovations of the museum's iconic Main Street facade. The beam will ultimately be enclosed, preserving the signatures as a time capsule. Attendees signing the beam will receive a special commemorative souvenir. John DeStefano of DeStefano & Associates, Inc., the Portsmouth-based construction management firm coordinating the museum’s renovation project, will be on hand throughout the event to answer questions. Visitors can tour the museum’s Salon Style and Treasures of the Community exhibitions and will additionally be treated to the debut of an all-new exhibit that presents the history of the museum’s 19th-century buildings and displays photos chronicling the current renovations. Included on view are a number of items—from an early light bulb to an unique patent medicine bottle—discovered over the past few months by the construction crews!
