A charming and heart-warming Mexico airmail issue celebrating the International Year of the Child (1979), featuring an authentic child’s crayon drawing titled “Dibujo de Adriana Blas Casas, 5 años.” The playful figures and earthy tones capture innocence and creativity, making this stamp both socially meaningful and visually distinctive. Issued as an aéreo (airmail) stamp, it blends postal utility with humanitarian messaging. The primitive art style and personal attribution to the young artist add strong thematic appeal. A delightful collectible for topical themes such as Children, UNICEF, Art by Children, and Social Welfare.
