Photo crop exposure date: unknown.
Exposure date (or window) of subject photo: 1897-1902.
Subject: Photo crop of a book page of a manipulated photograph of Main Plaza. View is WSW across the plaza. Almost certainly taken from the Kampmann building, showing the plaza park (1897), San Fernando Cathedral without the south tower (finished in 1902), the Frost Bank building (1871) and San Antonio City Hall (1892) with the two south conical roofs and the two north mansard roofs removed (almost) from the photograph, but still faintly visible.
