Wall 9 is very damaged, and only two significant areas of decoration survive, both of which are shown on this page. Both belong to a scene of Senneferi receiving his funerary equipment: the upper photo here shows the text, under which Senneferi would have been seated. The text here can be very much reconstructed on the basis of parallels from the nearby tombs TT85 and TT79: a man would have stood before Senneferi presenting the items to him. In TT99 the text begins with the word "his brother" and then there is a blank on the wall (fourth column of text from the left in the picture. Study in 1997 revealed that the colour of this blank is slightly different from the rest of the wall, so perhaps someone's name was removed. This is actually rather clear on the photo.
The right hand text is as follows (found in both TT85 and TT79):
"Sitting pleasurably in [his] house [on earth which is established in] Thebes near [(the house of) the lord of the gods after] returning from the Great House, [lp]h, [by] the iry pat, haty-a the one favoured of the perfect god [the overseer of seal-bearers Senneferi, true of voice], so that he may see his burial equipment and he may receive [his monuments of burial] and his statues of every august stone [which are intended for the temples in the praise of the perfect god]."
The left hand text is as follows (found in TT85):
"His brother (name not written) [says: for your ka, statues gilded with electrum and em]-bellished with [august stones of the god's limbs, monuments of burial and all good things of burial which are to be done for one praised of the perfect god], oil for embalming [the mummy, a coffin for uniting the corpse of a follower of the king, like what was done for] those of former times (and for) a follower of the king of all their times, the possessors of burial after [years] /// everything good ///."
