The collection includes glass plate negatives sizes 3x5 inches, 3.25x5 inches, 4.25x4.25 inches, 5x7.5 inches, 5x inches, 5x8.5 inches, and 21 acetate film negatives, size 3.5x5.62 inches. Topics include dynamos, industry, Great Lakes ferries, nature, baseball, parlors, buildings, railroads, lumber, ships, logging, mine shafts, people in Hurley, Saint Ignace, and Montreal, Michigan, near Marquette. It appears that negatives in boxes 1-3 were probably taken by W. Wells Lamb, a photographer from Glidden, Wisconsin. Other photographers are unidentified. Items were identified as much as possible from labels, slips of papers, notes on original boxes, and, whenever possible, information on/in the negatives themselves. Negatives with damage such as fading, spotting, oxidation, cracks, broken or missing pieces, deteriorated or flaking emulsions have been noted on the sleeves. (For information on Fred R. Trelfa see the finding aid to his other collections.) Boxes 1-8 measure 4x7x10.5 inches, smaller than a .5 cubic foot letter-size box.
