This semi-postal stamp from Spanish Guinea (Guinea Española) was issued to raise humanitarian aid funds for Valencia, Spain. The design prominently features symbolic doves of peace alongside heraldic shields representing Spanish unity and relief solidarity. The additional +10 céntimos surcharge was dedicated to charitable assistance, making this issue both philatelically and historically significant. Printed by F.N.M.T., it reflects Spain’s colonial postal contributions toward domestic relief efforts during the mid-20th century. A strong thematic collectible for charity, colonial, and humanitarian stamp collections.
