This is a dark-colored, horizontal wooden sign with a decorative trim, approximately 7 ft x 18 inches in size, clearly advertising the schedule for the U.S. Mail Boat service, which is historically operated by the M/V Sophie C. The service's name is rendered in large, bold white lettering across the center. Below, the operating season is specified in smaller yellow-gold text: JUNE 15 thru SEPT. 8. On the right side, a prominent red circular graphic highlights the daily departure times: DEPARTS 11:AM & 2:PM DAILY. The overall design is classic and rustic, suggesting this historic and seasonal transportation service, America's oldest floating post office, provided two daily trips to deliver mail to the islands of Lake Winnipesaukee during the summer season.
