ATQ Turn of Century Occupational Photos Trestle RR Bridge Construction Workers For Sale

Lot of two original antique boarded photographs depicting workers pausing for a group photograph during the construction of a trestle railroad bridge in the United States at the turn of the century. The two groupings appear to be entirely separate groups of men, perhaps working at different points on the same project. The images are black and white prints mounted on cardboard, 5.5 x 6.5 inches.
Condition overall is very good, with some corner and edge wear on the boards. One of the photo images is excellent. The other has a faded spot on the left edge of the image. Please review provided photos for final word on condition.
