A striking 25 céntimos charity issue from Spain, printed by Waterlow & Sons, London, depicting King Alfonso XIII in a finely engraved portrait. Issued to support the Spanish Red Cross, the design features rich carmine-red engraving, a crown and floral wreath surrounding the monarch, and the unmistakable Red Cross emblem at right. These semi-postal stamps were released during the early 20th century to raise funds for humanitarian work, making them cherished pieces among Red Cross and royal portrait collectors. Known for its crisp line engraving and bold colour, this issue remains a classic of Spanish philately.
