Banco de la Unión was one of the private commercial banks operating in Colombia under the free banking legislation of 1880, which allowed chartered banks to issue their own circulating notes. The arrangement lasted barely a decade — the Banco Nacional progressively squeezed out private issuers through the late 1880s and 1890s, and most of the Unión's notes were retired well before the bank itself ceased operations.

The American Bank Note Company produced this series from its New York shops, as it did for the majority of Colombian private bank issues of the period. ABNC's work for South American clients during this window was prolific enough that distinguishing one institution's plates from another requires close attention to serial typography and border details.
