Perhaps

we will have to agree to differ.
I think the thin vertical poles rising from the turrets are matched in the Graces' link picture I gave as well as the depiction of the building. Also the horizontal lines of the brickwork are depicted well in the engraving.
I am not sure whether the artist will have had a final building to work from in terms of depicting the picture. I think this building was built for the 1888 exhibition, so is it possible that the engraver was working from an architects drawing maybe, so didn't have the full picture of the building to see?
edited to add - Pete please can you add a clear picture of the engraved words and also a picture of each side of the glass? thanks
