POTSDAM -- The Potsdam Public Museum, 2 Park St., "history at noon" program will host Tom French for a talk on "19th Century St. Lawrence County in 3D" Tuesday, June 18.
The talk will feature an interactive presentation on 19th century 3D photographs of St. Lawrence County as well as a brief history of stereography.
Stereoviews were cards that depicted two slightly different views of a scene which, when looked at through a stereoscope, gave a 3-dimensional effect.
Stereoviews were popular in the United States from the 1860's into the 1930's.
