The north side of the Bonham Square, as it looked in 1860. Identified above are J. W. Newton Saddlery and Harness; W. H. Pierce Drug Company; and the David Rhine building.
Casie Partridge says:
Southside of the Bonham Square from the east about 1955 based on the 1955 chevrolet in front of the Alexander Hotel. Below the Hotel is a Jewelry Store (Sabine Valley no longer there), Grant Vogue (High end dress Shop), F.W. Woolworths, Whites Auto Store, Hunts Department Store (looks like Hunts has already expanded to the east into the former Best theater Building), can't make out the rest except Keene's Cafe, and of course the Bonham State Bank Building and across main to the west is the First National Bank Building.
