I presume so - this is November 1928, so this must be a Baird system TV.

Where’s the screen? That little disc?
Yes. Early TVs used a spinning disc with little holes in it, which is what takes up the rest of the cabinet. This design preceded CRT TVs. A bank of lights behind the screen switch in sequence with the disc to produce apparent lines which in composite form a very low res monochrome picture. I built one for a school science project back in the day., drilling holes in an old LP. We used a large fresnel screen to magnify it.

Most of the flowers on that chair fabric look like screaming faces, and if I was part of that upholstery I think I'd join in.

Also, with formal wear your socks should match either your shoes or your suit! Gah.

Perhaps the viewer is colour color blind but was chosen so that he could say (truthfully, as far as he was concerned) that the black and white images were in colour color.

France.
As Jan would point out, it looks as big as the real thing.
And It's clearly wasn't wireless in those days.

Can the driver see where he's going, or is he relying on the horse to react correctly when encountering other road vehicles (horse-drawn or otherwise) and pedestrians?
