Photograph of black bears eating in a forest landscape. Several black bears eating food can be seen in the middle of a field. Cardboard boxes and paper wrappers can be seen in the foreground. Dense trees grow on the outside of the field. Jefferson would often use the same negative to create a lantern slide as well as a mounted stereographic card. When possible we have indicated if it is a repeat image, however this is not always the case. As such, there may be a corresponding digitized glass lantern slide, and a mounted stereographic card associated with this stereographic negative within the Mark Jefferson Collection.

Black Walnut tree in Ypsilanti, Michigan. The tree stands by itself on the hilly landscape, which is covered with grass. Piles of sticks have been stacked in rows surrounding the tree. It appears to have been either fall or spring when the picture was taken because small leaves can be seen on the walnut tree.
