This vibrant 1981 Christmas semi-postal set from Panama, titled “Navidad 81 Pro-Ciudad del Niño,” features charming artwork created by 12-year-old Panamanian children. Each stamp carries a 2-cent surcharge benefiting the Ciudad del Niño (City of the Child) foundation. Designs by Eric Belgrane, Enrique Daniel Austin, Jorge Gonzalez, and Ricardo Morales capture the festive spirit through scenes of nativity, decorated trees, and joyful holiday imagery. A beautiful fusion of youthful creativity and philatelic charity, this set remains a favorite among collectors of Christmas and children’s art themes.
