This Yugoslav stamp, issued in 1968, marks the nationally observed Week of Solidarity (1–7 June), promoting humanitarian cooperation and social unity. The design features a symbolic illustration of a ruined building, paired with a red clock motif, highlighting the urgency of aid and collective action. Printed in a distinctive rose-red palette, the stamp carries a face value of 10 dinars and reflects the social-welfare messaging typical of late 1960s Yugoslav issues. A meaningful thematic piece for collectors of social history, Red Cross–related, or Yugoslavia commemorative material.
