The bank as it is now.

Given the history of the First National Bank of De Kalb, the bank pictured above may be it.

[The Rand McNally Bankers' Monthly. January, 1907]

The First National Bank of De Kalb lasted fewer than three years and was succeeded by the First State Bank on August 20, 1909.

[Annual Report of the Comptroller of the Currency 1909]

There are none reported in the census.
