Penobscot Marine Museum’s season-long, campus-wide exhibition “Summer Folk: The Tourists of Penobscot Bay” will be the focus of Penobscot Bay Day, an all-day celebration that includes free admission Saturday, Aug. 25.

“Summer Folk” explores changes in lodging, transportation, recreation, demographics and the social milieu of tourism through recreated hotel and guest house environments, vintage photography, old advertising and marketing materials, steamship memorabilia, postcards, antique sporting goods, clothing, boats and more.

When summer folk were not out on the water or on the golf or tennis courts, they played lawn games, cards and board games. On Penobscot Bay Day, visitors will enjoy all manner of summer games from bocci, badminton and croquet to backgammon, chess, checkers and, for the serious (or not so serious) gamers, a noon to 4 p.m. cribbage.

In addition to the games, featured events will include Touch Tank from 10:30 to 11:30 a.m. with oceanographer Mike Dunn; “Sea Lives,” the artworks of artist Sonja Weber Gilkey; “Gone Fishing: Maine’s Sea Fisheries”; “beach globe” making in the Boat House; local food vendors; and, from 2 to 5  p.m., live rock, folk, blues and Celtic music by Mike and Susie Fay Band from Penobscot.
