1.000 Sucres

The Banco Central del Ecuador had relied on ABNC for its high-denomination printing since the 1920s, and this 1,000 Sucres note falls within a series that bridged Ecuador's post-war economic stabilization and the currency reforms that eventually led to decimalization pressure in the late 1960s. ABNC's intaglio work on Ecuadorian notes of this period is generally considered among the finer examples of their South American output.

The twenty-three year emission window is unusually long. Notes from the early 1944 printings and those dated into the 1960s share the same fundamental plate design, though signature combinations changed repeatedly as central bank administrations turned over — identifying the precise issue date depends almost entirely on matching the printed signatures to known appointment records.
