Lot of 47 Vintage 35mm Color Photo Slides.  Boston, MA, 1976 Bicentennial Tall Ships and 1980 Operation Boston Sail Tall Ships (350th Anniversary of Boston).  About 50/50 1976/1980.  The photos here show a sampling, not all of the slides.  There's photo processor dates of June and July, 1980.  A group with embossed processor information which is unreadable, but I believe are part of the 1976 group.  And a group with handwritten captions indicating 1976.  These are amateur photographer views, some better composed than others.  The photos here are taken with the slides backlit against a computer screen, with resulting loss of clarity and some reflections.
