Issued by Brazil in 1955, this Cr$0.40 commemorative stamp honors the celebrated Brazilian writer Monteiro Lobato (1882–1948), one of the pioneers of children's literature in Brazil. The design features a detailed portrait of Lobato alongside a charming scene of a teacher reading to children, symbolizing his lasting influence on education and storytelling. Lobato is best known for creating the beloved Sítio do Picapau Amarelo series, which shaped generations of young readers. The engraving-style artwork and deep green tone give the stamp a classic mid-20th-century philatelic aesthetic. Collectors value this issue for its literary theme and cultural significance within Brazilian philately.
