Tv Tuning Cards & Test Signals

Before televisions started 24 hour broadcasting we used to see a tuning card and a test signal when we open the Tv. As those were the years we were kids (in fact I still do believe that I am a little kid) those test signals mean a lot to me... (Tho I used to hate them, today I love them, they are pretty retro and cool in my opinion) And when I start building web pages I love to use them instead of "under construction" notes...

Anyway; I love tuning cards; and here are some links you can find them and let yourself swim in the sea of nostalgia... ;)

The test card gallery: Lots of test cards and there also is an f.a.q section.
Art > Television > History > Testcards : Google has some links in its web directory...
And, sub-tv has some ancient test cards here...
