This obelisk of black alabaster was erected in the centre of Nimrud shortly before the death of King Shalmaneser III (858 - 824 BC). It records the king's wars, and shows tribute being brought to him from all directions. The inscriptions identify the sources of the tribute illustrated in the 5 rows of pictures as (from top row to bottom row):
- Gilzanu (Western Iran)
- Jehu of the house of Omri (ie. the Israelite)
- Musri (an unidentified country somewhere in the East)
- Suhi (on the middle Euphrates)
- Patina (Southern Turkey)
This photo gives a view of side A (right) and side D (left). For a translation of the inscriptions above the rows of pictures, see here. For a translation of the full text of the inscriptions, see here.
A reference to look up if you have the book: Mitchell, T. C., The Bible in the British Museum, (London: The British Museum Press) 1988, pp. 46-49.
But I think his identification of Musri as Egypt is rather doubtful, as the items coming from it suggest a country in the East. The current captions in the British Museum also suggest that it may be somewhere near India.
