"Relief of the god Seth from the pyramid temple"
The 12th Dynasty pyramid complex of Senwosret III (r. 1878–1840 B.C.)
Metropolitan Museum of Art, NYC

Dieter Arnold of the Met's Department of Egyptian Art says:
"King Senwosret III (r. ca. 1878–1840 B.C.) was one of the most powerful and important rulers of ancient Egypt. Key developments in religion, political administration, and the arts took place during his reign."

A photo of this relief also appears in KMT magazine, VOLUME 15, NO. 4, Winter 2004-05,
which explains it is "On a limestone block of a destroyed monument of Thutmose II, in the Open Air Museum, 18th Dyn."

Eugene Cruz-Uribe show a piece with a very similar Set relief in "Seth, God of Power and Might", Journal of the American Research Center in Egypt , issue 45:

Cruz-Uribe declares "This and the following blocks all appear to have come from some structure built and/or decorated during the reign of Horemheb at the end of Dynasty 18. The block shows a fragment of a scene where the god Seth, holding a crook, stands before the king (only a portion of the cartouch of Horemheb remains). (page 214)

Hm, I think it could be Amunhotep I, and here's why. While we see the arm holding the baton (Tcheser) in both their cartouches:


Horemheb's cartouche - Tcheser-kheperu-Ra ...


Amenhotep I's cartouche - Tcheser-ka-Ra Amenhotep I (Source Budge 2 Volume Dictionary set)

Tcheser-ka-Ra is more likely, because we can see half of the 'Ka' glyph:

Meanwhile, I love the strong linear aspects and attempted a version myself:
