The Banco Internacional de Costa Rica was created by government decree in 1914 as a state-controlled institution, effectively absorbing the note-issuing privileges that had previously belonged to a handful of private banks. This 20 Colones belongs to the bank's earliest emission, produced before it had the operational infrastructure to manage its own printing — hence the contract with the American Bank Note Company in New York, a standard arrangement for Central American issuers at the time.
ABNC plates from this period were often retained and reused across successive printings with minimal alteration, so date and series control numbers repay close attention when attributing individual specimens.
