The serekh of Double Falcon is unique. Firstly, it is the only one topped by two Horus falcons, facing each other. Secondly, the serekh does not have a place for the name. Instead this space is filled by vertical lines which usually represent the niched facade of a palace. The serekh does not have the horizontal line that separates the palace facade from the name of the ruler above. Finally, each falcon stands on its own peak. Experts believe that these features are symbolic. The two falcons could represent Lower Egypt and the Sinai, as it seems that Double Falcon reigned over both regions. Dreyer believes that the falcons stand on a on a sign meaning "mountain" which is N26 of Gardiner's sign list: N26 He reads the name as "Dju" ('), so that the name of the king is shown by a pair of falcons on mountains above a plain serekh. But another expert, van den Brink, reads the name as "Nebwy" ('), meaning "the two lords", and similar to a much earlier palette on display in the Barbier-Mueller Museum of Geneva.
