La Ofrenda study

This oil on canvas painting, measuring approximately 40 inches high by 32 inches wide (unframed) and 49 inches by 51 inches (framed), portrays a richly composed and highly symbolic scene that draws upon the cultural traditions of Mexico's Day of the Dead. The composition is dominated by large arch-like formations of bright orange floral wreaths, likely marigolds ( cempasúchil ), encircling the central altar area. Arranged around these arches are multiple candles, clay vessels, and communal offerings, creating a focal point that highlights a spiritual and communal ceremony of remembrance. A group of figures is gathered around this altar, most of them dressed in simple clothing reflective of i

Stretcher and Back Side

Closer examination of the reverse side confirms a relatively simple but functional wooden stretcher, likely dark-stained hardwood, with four perimeter bars joined at the corners. As seen in Figures -- , there is no evident crossbar or keyed supports, which suggests the original stretcher design was meant to secure a canvas of moderate dimensions without additional bracing. The wood exhibits a warm patina, possibly from age or staining, and bears a few small holes from previous hardware or re-stretching attempts.

The Original "La Ofrenda" Fresco by Diego Rivera

Among Diego Rivera's extensive body of work, the mural commonly referred to as "La Ofrenda" (also titled "The Sacrificial Offering Day of the Dead" ) stands as a seminal example of his engagement with Mexico's cultural identity and the burgeoning Muralism movement. Executed between 1923 and 1924 in the old Secretariat of Public Education building—now the Museo Vivo del Muralismo—this grand fresco measures approximately 415 centimeters by 237 centimeters. It forms part of Rivera's "Political Vision of the Mexican Pe

"Ribbon Dance" (1923--24)

Another notable fresco from Diego Rivera's prolific period in the early 1920s is "Ribbon Dance." Measuring approximately 154 inches by 11 feet 11 inches (4.68 m by 3.63 m), it occupies a prominent wall in the Court of the Fiestas at Mexico City's Ministry of Education complex. Executed between 1923 and 1924, this mural resonates with themes similar to Rivera's other works in the building: it celebrates Mexican cultural heritage, everyday communal life, and the vibrancy of collective festivities. In "Ribbon Dance,"

"Friday of Sorrows on the Canal of Santa Anita" (1923--24)

A grand fresco measuring approximately 15 feet by 11 feet 8 inches (4.56 m by 3.56 m), "Friday of Sorrows on the Canal of Santa Anita" adorns another wall within the Court of the Fiestas at the Ministry of Education in Mexico City. Painted between 1923 and 1924, it reflects Rivera's overarching vision for a new Mexican society—an idealized melding of revolutionary fervor, communal solidarity, and indigenous cultural motifs. Yet in contrast to the more traditional festivities captured in neighboring panels such as "

Signature Examination

Figure shows a close‐up view of the signature found on the oil painting. At first glance, it reads as "Diego Rivera" followed by numerals indicating a date. However, closer inspection reveals several anomalies in the letterforms (particularly in the "D," "g," and "R"), the spacing between letters, and the rendering of the numerals.

Reference Signatures from John Castagno's Compilation

John Castagno's Artists' Signatures and Monograms, 1800--1989 is a respected reference for verifying artists' inscriptions. Figure shows two authentic Diego Rivera signatures reproduced in Castagno's compilation. Again, the characteristic flow of the lettering and the spacing of the surname contrast with the questioned signature in Figure .
