Stereo analysis
AnalyzedVerdict
Genuine stereo pair97%
The two photographs contain the viewpoint difference needed to produce genuine depth.
- Depth spread
- 7px
- The range of horizontal difference between the two views. More spread generally means more depth; 0–1 px usually indicates a monoview.
- Match
- 98%
- 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
- 1px
- Vertical drift between matched details. Lower is better; 4 px or more can indicate camera movement, scan skew, or poor alignment.
A stereoview by P. B. Gaylord, identified by the photographer’s Duluth imprint along both sides of the yellow mount. The printed caption reads “View in Duluth Harbor.” The card belongs to the series “Scenery at the Head of Lake Superior,” and the vessel carries the name “QUEBEC.” prominently across its bow.
A plank wharf cuts diagonally across the foreground, beyond which the steamer lies among tall mooring posts. Its pale hull and the posts are reflected in still water. Figures sit outside the wheelhouse, with others visible on the deck below; a large, multi-storey waterfront building rises behind the masts and rigging.
The vessel’s painted lettering names the Lake Superior Royal Mail Line, the Grand Trunk and Great Western of Canada, and Sarnia, Ft. William, and Duluth. These inscriptions provide identification evidence beyond the mount’s general harbor caption. The waterfront building remains unidentified, and the card is undated.
The reverse is unprinted, with pencil notations but no descriptive caption or numbered checklist. There is a small loss to the yellow mount facing at the upper-left corner and a short dark scuff near the left edge of the right-hand image; otherwise the card is sound, with clear detail in both photographs.
