Vintage Brooks Brothers print

First, thanks for a very nice community, haven't posted before but followed for years.

I have this vintage print that I've been trying to get some clues about.
But haven't found anything like this anywhere.

It could be decoration from an old Brooks Brothers store or sold in store.
My guess is from late 40s, looking at the style.
On the back it says Made in England for Brooks Brothers. Sized 18.5" x 12".

Anyone with any knowledge please let me know.

The picture is "Regent Street Looking Towards the Quadrant" by TS Boys (1842). I believe that this would have been sold in store, given the back label; props. weren't labeled like this. Judging by the pictures I would put this in the early 1970s--simply because my parents have a lot of things in this style, from that period. I hope this helps!
