Vivid with revolutionary energy, this 1934 Mexican linen-era art card reproduces a detail from Diego Rivera's celebrated fresco Quema de los Judas (Burning of Judas) on the walls of the Secretaría de Educación Pública in Mexico City — one of the most important mural cycles of the 20th century. The composition surges with crouching laborers in blue trousers, a figure in a white sombrero draped in a red serape, and explosive cloud-like papier-mâché Judas effigies bursting overhead in dark carnival menace, all rendered in Rivera's monumental Social Realist palette of earthy reds, warm whites, and deep indigos. The card was printed in Mexico in 1934 by Von Stetten Color Foto for Mexico Tourist Service and distributed through the Fotolitografía Márquez press — making it a rare, early-production souvenir of Rivera's work issued during his own lifetime, just as his international fame was peaking following the Detroit Industry Murals controversy of 1932–33. Never mailed; the message side is blank.
