The designs on the reconstructed ivory veneer panels include six human figures in pairs, quadrupeds, birds, fish, and vegetal and geometric motifs. The ivory fragments — damaged and blackened by fire — were conserved and reassembled into panels by Judy Logan and Naif Zaban. The figures wear Persianate tunics over blousy pantaloons; four are in military dress and hold a long spear, seemingly evoking the rebellious activities of the Abbasids towards the mid-8th century. These remarkable ivories suggest a close affiliation between Humayma and the popular power base for the Abbasids in Khurasan, another testimony to the wide-ranging connections of this small site across the centuries.

A partially burned ivory plaque, found in the ruins of the early Islamic settlement at Humaymah in southern Jordan, dates from the mid-8th century AD. It was probably made in eastern Iran. Humaymah was inhabited by members of the 'Abbasid family before their supporters rose in revolt against the ruling Umayyad Caliphs in the eastern Iranian region of Khurasan.
