Sally Thibault, familiar to Vinalhaven audiences for her well-assembled slide show of island scenes covering 40 years of that community’s history, has now produced a DVD from the same material. “Vinalhaven — Maine Island Memories 1950-1990” is 37 minutes long, includes a nicely assembled soundtrack with selections from Dvorak and Elgar, plus Jim Wilson, Nick Apollonio and Kristen Tescher. The photographs, many of them by Thibault’s mother, Millie Cheney, and also by a variety of other island shooters, reflect Thibault’s discerning eye and provide a nostalgic look at island life as it was for four decades on Vinalhaven. The DVD is available at Archipelago, the Island Institute’s store in Rockland.
