Simpan Rahasia Negara dan Tentara

A propaganda poster created by Poesat Tenaga Peloekis Indonesia (P.T.P.I) in 1947 during the Dutch colonial war portrays a man quieting, symbolizing the imperative to maintain the nation’s secrets. The text, "Simpan Rahasia Negara dan Tentara," meaning “Keep the State and Army Secrets Safely,” emphasizes the importance of safeguarding vital information for the nation and its military. This poster is part of a scrapbook titled "We Struggle with Posters (P.T.P.I.)", containing reduced reproductions of P.T.P.I. posters from 1945-1947, addressing Indonesian and global issues.
