Jack Philllips, Pierceton, who has loaned more than 1,000 historic photographs for the Whitko Community Digital Image Project, displays one of his glass negatives created by Walter ‘Ducky’ Long in the 1910s and 1920s. The emulsion on glass negatives will flake off if improperly stored. Learn how to prevent this at the ‘Preserving Your Family Photos’ workshop Thursday. Photo provided.
