Behold, the bedroom of a serious Celtics fan. Painted the appropriate green with white wainscoting, the room is festooned with flags, decals, photographs, an adorable mini scoreboard, and a framed jersey representing Paul Pierce's Boston days. Naturally, the floor is covered with wall-to-wall Celtics carpeting, a perfect match for the team blanket on the bed. Alas, the maximalist decorating ends there and, for the most part, the rest of the Mashpee house is fairly subdued. The 1,679-square-foot Cape was built in 1993 (according to Wikipedia, "the first season since the 1978-79 season that Hall of Fame player Larry Bird was not on the team. This also was the final season for longtime Celtics all-star forward Kevin McHale.") and includes an open floor plan with a loft and two additional bedrooms, including that of a slightly less enthusiastic Patriots fan. Downstairs, the finished lower level offers a lesson in egalitarian decorating for superfans, with team swag from the Celtics, Patriots, Bruins, and Red Sox. Asking price for the .34 acre BYOB (bring your own banners) listing is $319,000.
