The collection was originally inventoried as including Saint Ignace and Les Cheneaux Island, Michigan, glass plate negatives, 1870-1880. Actually, most of the images are of Mackinac Island, Great Lakes ferries, and people, some of which may be from Saint Ignace and Les Cheneaux Island. The glass plate negatives measure 5x7 inches, 8x10 inches, 6.5x8.5 inches, and 8.5x10 inches. The photographer or photographers are unidentified. Items were identified as much as possible from labels, slips of papers, notes on original boxes, and on/in the negatives themselves. Negatives with damage, such as fading, spotting, oxidation, cracks, broken or missing pieces, and deteriorated, or flaking emulsions have been noted on the sleeves. The images are duplicated in the Saint Ignace-Mackinac Photograph File in the Clarke Historical Library’s Photograph Vertical Files Collection. Boxes 3-4 are Heavy and should be lifted with care.
