Stereo analysis
AnalyzedVerdict
Genuine stereo pair97%
The two photographs contain the viewpoint difference needed to produce genuine depth.
- Depth spread
- 5px
- The range of horizontal difference between the two views. More spread generally means more depth; 0–1 px usually indicates a monoview.
- Match
- 95%
- 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
- 3px
- Vertical drift between matched details. Lower is better; 4 px or more can indicate camera movement, scan skew, or poor alignment.
The sidewheel packet Lake Superior lies close to the riverbank, shown broadside with twin smokestacks, an elevated pilothouse and long, railed decks. Decorative arches run beneath the upper deck, while the large paddle box carries the vessel’s name and Keokuk Northern Line lettering.
The mount is headed “Minnesota Scenery.” and bears the imprint “Photographed by Hoard & Tenney, Winona, Minn.” These identify the published series and photographers. The particular landing remains unidentified: Winona is given as the photographers’ address, not as a caption locating the view.
Two arched-top photographs are mounted side by side on a green card with rounded corners. The unprinted reverse carries pencil numbers and codes, but no descriptive caption or securely interpretable date. No view-specific printed title or publisher’s view number is visible.
A pronounced vertical centre crease has cracked the mount’s surface, with small losses of green paper along the reverse. The photographic images remain intact to either side and are otherwise clean.
