The relief sculptures in the first series of photographs come from the upper facade of the Osario or High Priest's Grave. The photographs were taken outside the archaeological encampment in February 1998 and June 2000.

Two such reliefs were shown in the Maya exhibition that traveled to Venice and Mexico City in 1998 and 1999. Chichen Itza archaeologist Peter Schmidt described one of the reliefs in the exhibition catalog of which he was the co-editor (Schmidt et al. 1998: 532, fig. 67).

According to Schmidt, the figure is a dancer who holds "what seems to be a two-sectioned hand drum like that of Nabalam." He wears a cord belt and pendants similar to those of the supernatural beings called Pawahtuns who were believed to uphold the four corners of the universe. Schmidt describes the object in the figure's right hand:
The scepter represents an ideal transition between serpent scepters and those of the foot of the god Bolon Dzacab of the Classic Maya, and the fan with the serpent foot carried by the ancestral lineage of the Xiu in one of the first colonial documents in Yucatán.

Schmidt identifies cacao fruits among what appear to be grains, fruit, jewels and feathers surrounding the figure. He notes that cacao also appears together with the mythological birds, ninety-six in number, that adorn the upper levels of the Osario. Their faces are those of God K, the serpent-footed deity.

The iconographic program of the Osario also includes Venus symbols in both Maya and Mexican form, feathered serpents, cloud volutes and masks in the Puuc style.

Describing a second figure, who seems to be "captured at the moment of executing a whirling dance," Schmidt points to the bird mask and the tall tiara in the form of a spiral ending in merlons, with a flower in the center. The arms are extended rigidly, with one hand grasping a serpent-headed scepter and the other a musical instrument. Feathery "wings" hang from the arms.

In an article in Arqueología Mexicana, Schmidt (1999) describes the relief sculpture in the second series of photographs as a man with attributes of a serpent and a bird.
