Looks like a good Studio photo to me. Looks like they placed the Harris and Ewing imprint on a piece of glass in that bottom corner of the negative when they made the print rather then opt for an embossed or a blind stamp imprint, or scrawl directly in the negative itself.

As has been alluded to already, Brown Bros. cannibalized lots of other photographers archives during that time period. Kept some of the originals and copied many of the originals along the way. Rarely took their own photos in my experience. A Brown Bros. stamp is not really a clue of Photo type at all.
