The Taller de Gráfica Popular (Popular Graphic Workshop, TGP) was a printmaking collective founded in Mexico City in 1937 by artists Leopoldo Méndez, Pablo O’Higgins, and Luis Arenal. Their aim was to use art to fight fascism and advance revolutionary social causes. In this poster, Homar uses the figure of the calavera (a skeletal representation of the human form, often associated with the Day of the Dead) from Mexican popular culture. The motif frequently appears in TGP prints. The TGP was very influential among printmakers like Homar, Carlos Raquel Rivera, and Rafael Tufiño, who were exposed to its work through exhibitions and reproductions. Black American artists, most notably the couple Charles White and Elizabeth Catlett, also went to work at the TGP in Mexico City in 1946.
