El Banco Internacional de Guatemala was one of several private banks of issue operating under Guatemala's 1874 banking law, which allowed chartered institutions to circulate their own notes alongside — and often in competition with — government-issued currency. The bank struggled through the Estrada Cabrera years, a period when political favoritism heavily skewed which private banks received government deposits and customs revenue concessions, effectively determining which survived.

Pick S153 falls in the "S" private/provincial series, meaning documentation on exact print runs and contracting printers remains incomplete in most standard references. Attribution to a specific security printer for this issue is not firmly established in the literature.
