Not sure what type of references you're looking for, but there are some descriptions on the Wikipedia page of the tomb TT55. Based on the description, I would guess this is one of the reliefs showing him and his wife on the eastern side of the main hall. One of the sources says it depicts a banquet and that his wife was called Merit-Ptah (see also here; this page is about a different person but also mentions TT55). There are more images on Wikimedia Commons with some more in the "reliefs" subpage. This one looks like the one in your post.
