"R. E. Trabue proudly put his name atop the building that, then as now, provided the largest commercial space on the square. A crowd of men seems to be attracted by the 'low prices' advertised by Trabue, while the man in the white shirt in the foreground apprarently is dealing in horseflesh. The white one-story building in the middle of the block was a saloon (Courtesy PCHS)" (Bill O'Neal. 2009. Carthage. Mount Pleasant, NC: Arcadia Publishing. P. 63)

The bank would be the building to the right of the saloon.
As is commonly the case, there is much more life on the street 100 years ago than there is now.
