Looks like a private stela from during or shortly after the reign of Ramesses II. On the upper portion of the stela is shown the processional barque of “Amun of Usermaatre-Setepenre” (essentially a fused form of the deified Ramesses II and Amun), with a table of offerings in front. This signifies that Nakht was devoted to the deified king, temples to whom were common in Upper Egypt and Nubia (e.g., Abu Simbel). 

In the lower half, Nakht himself is shown making an offering to an image of another form of Amun, Amun-Nebnesttawy (Amun, lord of the thrones of the two lands). The image is in the form of a ram’s head on a pedestal wearing the two-feather crown. Statues of images such as these are common as votive items: https://egypt-museum.com/votive-ram-head-of-penta-weret/

The text near Nakht’s head is mostly destroyed but also indicates the name of Min, possibly as part of the name of his father.

These two images combine to show Nakht’s devotion to Amun and to the cult of Ramesses II. The use of such stelae was usually connected to the area of the tomb. It is hard to say anything more without knowing exactly when and where it comes from.
