Stereo analysis
AnalyzedVerdict
Genuine stereo pair97%
The two photographs contain the viewpoint difference needed to produce genuine depth.
- Depth spread
- 10px
- The range of horizontal difference between the two views. More spread generally means more depth; 0–1 px usually indicates a monoview.
- Match
- 89%
- The share of usable picture detail that can be matched between the left and right views. A higher number means a more reliable comparison.
- Vertical
- 2px
- Vertical drift between matched details. Lower is better; 4 px or more can indicate camera movement, scan skew, or poor alignment.
A bear fills the foreground, upright against a tree trunk with its head turned to the left and a forepaw resting on a slanting branch. Bare limbs cross above its head; foliage and rough stonework fill the background. The close framing preserves considerable detail in the fur, bark, and stone.
The mount bears the heading “Wayside Gems” and the caption “1117. One of the Bears in Lincoln Park Chicago.” This printed identification establishes the stated location; the bear’s species is not specified.
The left margin reads “Published and for Sale by H. H. Bennett, Kilbourn City, Wis.” The opposite margin carries “Wanderings Among the Wonders and Beauties of Western Scenery.” Bennett is thus documented as publisher, though the imprint does not separately credit the photographer. No date is visible.
The two arched-top photographs are mounted side by side on an orange card with rounded corners. The reverse is unprinted apart from a small pencil notation. Fine surface crazing is visible in the photographs, particularly in the darker passages; otherwise the card is clean and sound.

Catalogue details
Location
Lincoln Park Zoo area, Lincoln Park — historical bear enclosure, exact position unresolved · Chicago, Illinois, United States
Photographed subject · Street / district · 60% confidence
Bachrach documents bears in the zoo’s nineteenth-century collection, replacement bear pits under construction in the late 1870s, and a historical bear-in-tree photograph held by Chicago Public Library. This supports interpreting the captioned scene as the zoo’s bear enclosure, but does not identify this stereoview, its exact enclosure footprint, or the camera position. Mapcarta supplies the stated coordinates for Lincoln Park Zoo generally; they are only a representative area marker.
