José Guadalupe Posada was a Mexican illustrator and printmaker, born in 1852. He is best known for his calaveras, or skeleton illustrations, which became iconic representations of Día de los Muertos (Day of the Dead). His work often combined humor and social commentary, reflecting the struggles of the Mexican people during his time. Posada's art played a significant role in shaping Mexican culture and identity, especially in the early 20th century. He influenced many artists, including Diego Rivera and Frida Kahlo, and his legacy continues to inspire contemporary art. Posada passed away in 1913, but his work remains celebrated today.
