Stereo analysis
AnalyzedVerdict
Genuine stereo pair97%
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
- 100%
- 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
- 0px
- Vertical drift between matched details. Lower is better; 4 px or more can indicate camera movement, scan skew, or poor alignment.
A steam locomotive and freight cars cross a long, low timber trestle over open water. Rails and exposed ties run diagonally through the foreground, among cut trunks, roots, and loose timbers. The paired images give a clear account of the trestle’s closely spaced supports and diagonal bracing.
The faint pencil caption on the reverse reads “N. O. M. & T. R. R.” and “Freight train crossing the bay St. Louis”. It identifies the crossing as the Bay of St. Louis in Mississippi. The initials appear to refer to the New Orleans, Mobile & Texas Railroad, although the letter following the ampersand merits confirmation.
A pale, partly clipped mark at the lower right of the right-hand image appears to be the negative number “70”. There is no matching reverse catalogue: the otherwise plain back carries a separate ink “#53” and the inscription “R. Grzegowicz Collection LEB WI.” Neither number establishes a photographer or publisher, and no maker’s imprint or date is visible.
Mounted on yellow card, measuring 6.9 × 3.39 inches as supplied. The image is light in tone but retains readable detail. Localized tide-mark staining is visible on the reverse; otherwise clean and sound.
