The Banco Central de Reserva de El Salvador relied on U.S. printing houses for much of the mid-century series, and USBnc was the less prominent of the two major American security printers — a distant second to ABNC in both volume and prestige. Their Salvadoran contracts from this period are relatively understudied, and the P#113 sits in a run that saw fairly heavy circulation use given El Salvador's active coffee and trade economy in the early 1970s.
The single watermark as the sole security feature reflects the modest anti-counterfeiting expectations of the era for this denomination — thread and color-shift would come later in the series.
