Although Maler reported remains of masks and other stucco decorations on this building, the remains he saw are long gone. Discovery at Acanceh's main building of this and three other large masks was carried out only in the course of very recent excavation work. This particular example is well preserved only in the earflares. These display most of the elements found in representations of architectural masks elsewhere in the Maya area, to wit: the knots under and above the earflare proper and the foliation that seems to grow from the upper portion of the earflare. The destroyed elements in this mask, modelled in painted stucco, reveal the stone armature over which the stucco was applied.
