Banco Oxandaburu y Garbino was a private Argentine commercial bank operating in Corrientes province — one of several regional institutions that issued their own paper currency during the chaotic decades before Argentina established a unified national banking framework. The 1869 date places this note squarely in the post-Paraguayan War period, when Corrientes, having been invaded and occupied by Paraguayan forces in 1865, was rebuilding both its economy and its commercial institutions.

ABNC produced plates for dozens of South American private banks during this period, and the print quality is typically superior to anything achievable domestically. The PS prefix in the Pick catalogue denotes private and commercial bank issuance — not state-backed currency — and surviving examples are genuinely uncommon given the limited operational lifespan of most provincial Argentine banks of this type.
