A broken, decayed piece of a tablet, 31 × 12.5 × 2.5 cm of unknown wood.
Métraux (1938) said of the Honolulu tablets T and U that, He was of the opinion that T had once been a fine artifact: Collector J. L. Young of Auckland purchased three of the Honolulu tablets circa 1888 "from Rapanui through a reliable agent", who Fischer (1997) thinks was probably Alexander Salmon, Jr.
Ta is the only text, apart from the single line of Gv which Butinov and Knorozov suggested might be a genealogy, that parallels the glyph triplets of the Staff (Pozdniakov 1996).
It is the only other text that includes line breaks (one in Ta4 and another in Ta7) which dominate the Santiago Staff.
Fischer (1997) made pencil rubbings of this side, but the results were too faint to be legible.
