Illustration by Almendáriz of a stuccorelief at Palenque. The relief, dating to ca. 670CE, appears on the exterior face of Pier E in House A, part of the central complex of buildings known as the Palace (el Palacio).The drawing is a copy made from the original (now lost) engraving executed by Almendáriz during his visit to the site in 1787.

Almendáriz made thirty drawings of the bas relief sculptures at the Palenque ruins. These drawings were intended to accompany del Río's written report, which was dated June 24, 1787. According to George Stuart, writing for the Kislak Foundation, the del Río report "ranks as the first substantial archaeological report known in the Americas." Almendáriz's drawings of Palenque are "remarkably accurate for the era" and depict features of Palenque that have since been destroyed from exposure. For this reason they remain scientifically useful.
The Almendáriz drawings were copied for archival purposes. The most complete set of contemporary copies belongs to the library of the Royal Palace in Madrid.
