This is a vintage poster, approximately 24.5 x 17.5 inches in size, advertising the M/S Mount Washington's Dinner Dance Cruise. The poster uses a lavender and dark purple color scheme with the prominent title "Some Enchanted Evening" arched across the top, above an illustration of the vessel's silhouette against a starry night sky, labeled "the Big Lake... the Big Boat." A large collage of photographs shows people dancing, dining, and socializing, capturing the atmosphere of "New Hampshire's most exciting Dinner Dance Club." The poster highlights the cruise features: "Two Bands, Three Lounges, Sumptuous Dinners," and activities like "Dancing, Fun, Romance." Contact information in yellow text encourages people to "call 366-BOAT for information & reservations," and the bottom notes the operator as "Mount Washington Cruises" in Weirs Beach, NH.
