Dallas Public Library has this photo online:
Dated October 10 1925.
A key landmark, still seen on maps today, is the railroad spur that swings south under the plant.
During the early decades of its development, Cement City was considered a separate town with its own PO designation by the post office.
From what I've read, I tend to think the governor's mansion was about 1/4 mile south and east of the plant as shown in this photo, but there are few geographical markers to show where the bluffs were.
