Genuine stereo pair87%
The two photographs contain the viewpoint difference needed to produce genuine depth.
- Depth spread
- 2px
- 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
- 1px
- Vertical drift between matched details. Lower is better; 4 px or more can indicate camera movement, scan skew, or poor alignment.
Seen from an elevated position, a dense crowd gathers around an equestrian monument at the edge of Union Square. Beyond it, pedestrians cross the broad roadway, horse-drawn carriages stand along the park fence, and street-railway tracks curve through the foreground. Bare-branched trees reveal the paths within the square; substantial buildings line its far side.
The reverse label identifies the scene as “The Great Union Meeting, Union Square, New York, April 20, 1861.” The number 908 within the lower-right portion of the left image matches the label’s No. 908, directly linking the photograph to this Union gathering at the opening of the Civil War.
Published by E. & H. T. Anthony & Co., whose reverse imprint gives the American and Foreign Stereoscopic Emporium at 501 Broadway, New York. The label supplies the date of the event, not necessarily the date this example was printed and mounted; it does not name the photographer.
An ink inscription across the upper mount reads “Nuova York Parlamento.” Its writer and date are unknown. The paired photographs are mounted on yellow card. Small brown spots occur in the upper-right sky, with scattered spotting on the reverse label; otherwise the card is clean and sound.
