Flute of Aztec origin made out of a human tibia. It’s single sectioned and it has only got one hole. This hole was made from transversal cuts on the bone, and it is black inside, as opposed to the bone color of the rest of the instrument. The 1905 catalogue of the Delgado de Carvalho Museum mentions that there are hieroglyphs drawn with ink along the instrument’s body, however these drawings are no longer visible.
