Test Card Gallery

I came across this image on Flickr today. It took me back. Way back.



Then I discovered a BBC Test Cards gallery.




According to the website, Test Card C (Digitally remastered) as shown above was "immensely popular". That's wonderful, but with who I wonder? And how could you register your approval for such things?

Whilst I'm here - let's take a balanced view. Who remembers Widespread World of Rediffusion? I don't really, but my Grandma used to own Rediffusion Television set even into the early 1990's. Beautiful logo.
