This Notice to Owners of rubber land between 35 and 140 relongs in extent offers a rare glimpse into Malayan postal history and rubber industry regulation from 1934. A relong is a traditional Malay unit of land area, historically used primarily in Kedah and Penang, equivalent to roughly 0.71 acres. This document vividly captures the Rubber Regulation Scheme in action following the collapse of rubber prices, serving as a unique piece of ephemera for collectors. At Jackaw, we value the preservation of such significant historical artifacts, providing enthusiasts with authentic items that reveal the economic and postal narratives of the past. This piece enriches any collection with its blend of postal history and industrial heritage.
