Banco del Ecuador was a private commercial bank operating out of Guayaquil, not a central bank — Ecuador had no central monetary authority until the Banco Central del Ecuador was established in 1927. Several competing regional banks issued currency simultaneously during this period, and the Banco del Ecuador was among the most prominent, closely tied to the coastal export economy built on cacao.

The American Bank Note Company produced currency for dozens of Latin American issuers from its New York facilities, often reusing plate elements across clients. The P#141D designation suggests this falls within a longer series with multiple signature or date varieties, worth cross-referencing carefully before attribution.
