Monoview (identical duplicate)72%
A monoview: the same photograph printed twice, so no genuine stereoscopic depth is present.
- Depth spread
- 1px
- The range of horizontal difference between the two views. More spread generally means more depth; 0–1 px usually indicates a monoview.
- Match
- 99%
- 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.
The Iroquois is shown broadside on the water, its twin funnels sending a dense bank of smoke above the decks. People stand along the railings, with American flags flying fore and aft. Waterfront buildings, a long trussed structure, and a hillside dotted with houses fill the background.
The printed caption reads “Steamer Iroquois. W.L.T.CO.” The vessel’s name is also visible on its hull. L. E. Westberg’s mount imprint gives his address as 106 1st Avenue, West, Duluth, Minnesota. No date or publisher’s view number is visible. The precise waterfront is not identified by the caption; Duluth appears as the photographer’s business location.
Both sides bear Northwestern Paint Co. stamps, the reverse giving 323 W. First St., Duluth, Minn. A faint but largely legible pencil note reads: “She is the pride of Lake Superior / and how can she help it / She is painted with S.W.P. / Sold by the”. The paint initials are tentatively read as “S.W.P.”; the final words lead directly into the company stamp. This inscription gives the card a specific paint-trade association and links the vessel with Lake Superior, without naming the particular harbour shown.
Two rounded-top photographic images are mounted side by side on a gray-faced card. A small red mark is present at the right mount edge, clear of the photographs; the images are clean and the card otherwise sound.
