New Street Signal Box Brutalist Architecture Illustration Set

This brutalist box sits neatly tucked into the cityscape, next to the red cage carpark as you leave one of the many exits from New Street Station. Designed by Bicknell & Hamilton and W.R. Healey  and built in 1965, this beauty received Grade II listed status in 1995, inside and out including the interior (go have a look, its pretty cool seeing all the wires and stuff!) meaning my heart can stay happy that it won't have the same sad fate as Birmingham Central Library. 
Commonly called an eyesore, it sticks to the very Brutalist Brummie way of not really caring if you like it or not, and I think that's what I love the most. Sadly the actual job they do inside is slowly being consolidated so the need for signal boxes will soon be obsolete. 
This set of three sketches are drawn by myself using ink pens and posca pens for those bright, impactful elements. They are all roughly 17.5cm x 12.5cm (give or take a few mm), on 300gsm card and come unframed. The frames in the photographs are 5x7" (13 x 18cm).
