1940's Dr Who Dalek To Victory Poster

Spotted this poster in the latest series of Dr Who.
The Doctor travels to wartime London, where Churchill is using daleks in the war effort.

As soon as I spotted the poster, I texted my Dr Who mad brother to see if he could find me one on the forums.
He found one on the BBC Dr Who site for me.
I plan to hang a Keep Calm and Carry On poster beside it, rather than the out-of-era 1960's creepy child painting.
