Issued by Deutsche Bundespost in 1967, this 30-pfennig stamp commemorates the 450th anniversary of Martin Luther’s Ninety-Five Theses, posted on October 31, 1517, an event that ignited the Protestant Reformation. The bold red design depicts Wartburg Castle, where Luther later translated the New Testament into German. The clean, stylized imagery and minimalist typography reflect mid-20th-century German design sensibilities, making it a striking historical and artistic piece valued by collectors of religious and Reformation-themed issues.
