Stereo analysis
AnalyzedVerdict
Genuine stereo pair97%
The two photographs contain the viewpoint difference needed to produce genuine depth.
- Depth spread
- 6px
- The range of horizontal difference between the two views. More spread generally means more depth; 0–1 px usually indicates a monoview.
- Match
- 93%
- 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.
A full-length studio portrait in two arched-top photographs on a yellow stereoview mount. The sitter stands turned slightly to the left, wearing a feather headdress with a long train falling behind him. His torso is bare; a dark, light-bordered apron, leggings with triangular side panels, and decorated moccasins complete the dress.
The painted backdrop depicts mountains, water and foreground foliage. A vertical support and the edge of the backdrop remain visible at the left, with hanging fabric above and wooden floorboards below. These details locate the portrait within a photographic set rather than the landscape represented behind it.
The otherwise unprinted reverse bears the faint pencil caption “Sioux Medecine Man”, retaining the apparent spelling of the inscription. This records the identification written on the card; the sitter is not named, and his tribal affiliation and stated role cannot be confirmed from the photographs alone. No photographer, location or date is established.
An additional pencil number, “1193”, appears on the reverse, but no matching number is discernible on the front. Its purpose is unknown. The supplied card dimensions are 6.93 × 3.47 inches (176.0 × 88.1 mm). Localized marginal staining is most evident along the lower reverse edge; otherwise the photographs are clean and the card appears sound.

Photographed subject · Locality (town) · 75% confidence
Card names no place and the back is blank, but the painted river-and-mountain backdrop with plank floor is the documented signature of James H. Hamilton's Sioux City, Iowa studio portrait series "Stereoscopic Views of the Northwest" (Sioux delegation portraits, 1870s). The Smithsonian NMAI (Gurnsey/Hamilton collection) and American-Tribes research identify this exact backdrop as Hamilton's Sioux City studio; he operated there from October 1868. Studio street address not verified, so pinned at downtown Sioux City.
