Issued in 1967, this 0.25 Israeli stamp commemorates 30 years since the beginning of Aliyah Bet, the clandestine immigration of Jews to Mandatory Palestine despite British restrictions. The dramatic design shows a shadowy immigrant ship under moonlight, symbolizing secret maritime journeys made by Holocaust survivors and refugees. The Hebrew inscription at the top translates to “Thirty Years to the Aliyah.” This evocative issue highlights Israel's historical struggle for Jewish repatriation and national rebirth.
