Aklan was one of several Philippine provinces that organized its own emergency currency board after the Japanese occupation disrupted the existing monetary system in late 1941 and early 1942. These provincial issues were explicitly temporary instruments, intended to keep local commerce functioning while the Commonwealth government's reserves were either evacuated or inaccessible. The Aklan board produced one of the smaller series, with denominations kept low to match actual market conditions under occupation.

At 53 × 34 mm, this is among the smallest emergency notes produced anywhere in the Philippine archipelago during the war — a function of paper scarcity, not design preference.
