Names on the sign
The FDIC office number stays with the building when banks merge or rename, so the same office appears under each owner. Follow an earlier name to see what became of that bank.
Deposits are the balances the bank assigned to this office on June 30 of each year, in nominal dollars. Source: FDIC Summary of Deposits, office (UNINUMBR) 14615.
