One side of this plaque is etched with a standing human figure. The figure faces left, with his right hand raised and gesturing, and his left arm hanging down at the side. His head is broken off at the top. He wears a large necklace, bracelets, and anklets. His skirt is topped by a woven belt with a deity-head ornament and three hanging celts. Elaborate leggings support a monster head ornament at each knee.
The back of the plaque bears a double panel of glyphs, possibly the earliest dated Maya text known to scholars. The inscription consists of a date, probably 18.104.22.168.0. (July 15, 150 CE), followed by the name of a ruler. The glyphs are read in pairs, from top to bottom, and the last one may be an early form of the ahau title of nobility.
Three holes drilled into the plaque suggest that it was hung in several different orientations over time.
