Stereo analysis
AnalyzedVerdict
Camera moved / alignment issue75%
The pair does not align reliably enough for a trustworthy depth reading; scan skew can also contribute.
- Depth spread
- 5px
- The range of horizontal difference between the two views. More spread generally means more depth; 0–1 px usually indicates a monoview.
- Match
- 97%
- 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
- 5px
- Vertical drift between matched details. Lower is better; 4 px or more can indicate camera movement, scan skew, or poor alignment.
Several dozen men, women, and children pose outside a two-story clapboard building in this stereoview bearing the imprint of Blair & Son. The group fills the porch and extends onto the bare ground in front, with seated figures below and standing figures arranged between the porch posts. Large painted lettering across the upper story is cropped at the left; the visible portion reads “T HOUSE.”
The photograph records considerable variety within the group: men in bowler and brimmed hats, women in long dresses and elaborate hats, and children seated among the adults. Some sit on the porch edge, others directly on the ground. The building’s sash windows, shingled roof, and chimney remain clearly visible above them.
The pink reverse is printed “Blair & Son,” followed by “Portrait and Landscape Photographers,” “411 Main Street,” “Worcester, Mass.” and “Out-Door Views, Groups, &c.” Worcester is the photographers’ address, not an established location for the scene. An isolated pencil notation at the lower right appears to read “524,” but supplies no identification. The building, sitters, occasion, and date remain unidentified.
Two warm-toned photographic images are mounted side by side on an orange card with rounded corners. The photographs are clean and intact, and the card is otherwise sound, with no significant damage visible.

Painted sign reads "…T HO[window]USE." — identical lettering, window placement and reversed-style E to NYPL Robert N. Dennis stereoviews titled "Summit house on Mt. Wachusett showing large addition and guests on porch." Verso "Blair & Son, 411 Main Street, Worcester" is the photographer's studio, not the scene. Not the Leavitt House, Pine Point (that guess was unsourced). Coordinates: Mount Wachusett summit (Google Places).
