Help finding correct tile

[Luka Jozic]

This is a long shot, but I gotta try. I just purchased a SFH in Cleveland. The bathroom has some unfinished tile and the seller claims they don't have any left over but that I should be able to find the same at Lowes. I have looked and cannot find it. I was wondering if there are any experienced rehabbers here that maybe happen to recognize this tile or can at least give me some pointers that can narrow my search? The one Im looking for is the smaller tiles on the left in the image.
