[3][4] The prenomen Nebmaatre is attested on a bronze axe-head discovered in a tomb at Mostagedda in Middle Egypt and now in the British Museum under the catalog number BM EA 63224.

The same prenomen is inscribed on a black steatite amulet representing a lion of unknown provenance and now in the Petrie Museum under the catalog number 11587.

However, the axe-head can be dated to the late Second Intermediate Period based on stylistic grounds and provenance while according to Flinders Petrie the amulet is of too rough a workmanship to be attributable to Amenhotep III.

[5][6] Instead, Petrie suggested that the amulet be attributable to Ibi, an obscure ruler of the late 13th Dynasty whose prenomen is partially preserved in the Turin canon as "[...]maatre".

However, Kim Ryholt's recent study of the Turin canon precludes this identification as a vertical stroke in the lacuna just prior to "maatre" rules out the hieroglyph for "neb".
