Johor: 300 Early Postcards is the sixth book of early picture postcards by Dato’ Pofessor Dr Cheah Jin Seng. The book contains picture postcards of the Malaysian state of Johor, which offer a rare opportunity to view the architecture, landscapes and lifestyles of a bygone era, from the late 19th century to the 1950s. The book begins with a brief history of modern Johor and its postcards and includes chapters on royalty, royal visitors and government; the Johor-Singapore causeway; the capital, Johor Bahru; and the towns, people, economy, flaura and fauna of the state. It concludes with a history of deltiology and philately in Johor.
