Issued by Germany (Berlin) in 1972, this elegant Wohlfahrtsmarken (Welfare / Semi-Postal) set features stylized chess pieces rendered in a modern graphic style. Each stamp carries a surtax (e.g., 30+15, 20+10, 70+35, 40+20 Pfennig) in support of charitable causes, reflecting the long German tradition of semi-postal welfare issues. Printed for Deutsche Bundespost Berlin, the designs combine cultural symbolism and mid-century aesthetics, making the set popular with thematic collectors (chess, games) as well as Germany/Berlin specialists. A desirable post-war Berlin issue, especially attractive as a complete matched set in fine condition.
