Issued by Belgium in 1973, this 3 franc stamp belongs to the Jeugdfilatelie – Philatélie de la Jeunesse (Youth Philately) series, which encouraged stamp collecting among young people. The design depicts a stylized painting of a young girl holding flowers, rendered in vivid, modernist tones that echo Belgium’s postwar art movements. The background shows an interior scene with framed pictures and a chair, emphasizing youthful innocence and artistic expression. A charming issue that blends fine art and philatelic education, appealing to both art and youth theme collectors.
