Stereoscope and View-master
The “Oh You! Scraggy Club” was apparently a hunting club active in the southern-central part of Nova Scotia around 1910. The club was apparently located in the Loon Pond-Scraggy Lake area.
None of the people in the photos are identified but five of the three-dimensional images have some writing on the back. The collection also includes a viewer for the images called a Holmes stereoscope.
