The Banco Internacional de Costa Rica was the country's state-owned commercial bank, established in 1914 to break the grip of private banking monopolies — the Banco de Costa Rica chief among them. By 1935 it had become the dominant issuing institution, though that position would not last: a 1936 monetary reform consolidated issuance under the government, and the Internacional was absorbed into the newly created Banco Nacional de Costa Rica in 1936, making this among the final notes issued under the Internacional name.

The American Bank Note Company printing is typical for Costa Rican issues of this period. ABNC held the contract for most of the country's currency throughout the early twentieth century.
