Pick 82 was issued across a six-year window during which Thailand was deeply enmeshed in the Vietnam War's regional fallout — U.S. military bases on Thai soil generated significant cash circulation pressure, and smaller denominations like this one turned over rapidly in local commerce around those installations. The note was printed by Thomas De La Rue, as with most Bank of Thailand issues of the period.

The series is straightforward to source but harder to find without the horizontal fold lines that heavy street circulation left on low-denomination notes of this type.
