The reverse is entirely plain with no printed design or text, save for the perforated word BETAALD visible in mirror image through the paper, a faint violet stamp impression at upper left, and minor toning consistent with the note's wartime emergency issue origin. |

Kaboepaten Laboean Batoe was one of dozens of Indonesian regional authorities that issued their own emergency currency during the Indonesian National Revolution. With Dutch forces reoccupying coastal trade centers and the Republic's central supply lines fractured, district-level administrations in Sumatra improvised local paper money to keep commerce and government payrolls functioning. These kabupaten issues were never coordinated into a unified system — each was a local solution to a local crisis.
Rantau Prapat, the administrative seat of Labuhanbatu, sits in the Sumatran interior tobacco and rubber belt. The printing was almost certainly done with whatever press equipment the district could access in 1947, which is why condition varies so dramatically across surviving examples of this series.
