Stereo analysis
AnalyzedVerdict
Genuine stereo pair93%
The two photographs contain the viewpoint difference needed to produce genuine depth.
- Depth spread
- 4px
- The range of horizontal difference between the two views. More spread generally means more depth; 0–1 px usually indicates a monoview.
- Match
- 91%
- 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.
Sea lions gather beside an arched rockwork shelter beneath overhanging foliage. One lies across a low rock at the waterline, another raises its head from the pool, and others sit near the dark entrance. Rippled reflections fill the foreground, contrasting with the sharply defined stonework and the animals’ smooth coats.
The mount identifies the scene as “1116. Sea Lions in Lincoln Park Chicago.” beneath the heading “Wayside Gems.” The left margin reads “Published and for Sale by H. H. Bennett, Kilbourn City, Wis.”; the right carries the series wording “Wanderings Among the Wonders and Beauties of Western Scenery.” The imprint establishes Bennett as publisher but does not separately credit the photographer.
The two arched-top photographs are mounted side by side on an orange card with rounded corners and ornamental printing. The reverse is otherwise blank apart from a small pencil notation at lower right. No date appears on either side. The images retain clear detail, and the card is clean and sound overall.

Location
Historic sea-lion pool/grotto, Lincoln Park Zoo (approximate zoo-area location) · Chicago, Illinois, United States
Photographed subject · Street / district · 60% confidence
The zoo’s history records construction of the original sea-lion grotto in 1879 and identifies its cover image as the original pool photographed around 1900. Together with the supplied mount title, this supports identification as Lincoln Park Zoo’s historical sea-lion enclosure. It does NOT establish the exact rockwork footprint, the camera position, or a match to stereoview 1116. Coordinates are the published general Lincoln Park Zoo point, used only to locate the surrounding zoo area—not the historical shelter.
