I'm guessing the first endcap (top) is from some point in 1973, as, like the previous ones, it has no date on it.
Robert Greenway asks: "I'm sure that, in the seventies (I think 1973), whilst I was at school, we had an English programme called You're Telling me. This ended with the ATV in a box end cap, but had "An" above it. I wonder if anyone else remembers this?"
Can anyone verify?
The different shades of blue on these two endcaps (top and bottom) could be a combination of three things:
- A physcially different coloured background;
- Colour balance of the telecine machine;
- The top endcap is from VHS, and in turn probably came from a format such as N1700, so the different video formats may have altered the colours.
The bottom endcap is from 1973. The proportions of the logo and text are different than in later endcaps, but similar to the one above. The text that says "COPYRIGHT ATV NETWORK..." is in a similar (could well be the same) font as the "AN ATV COLOUR PRODUCTION" endcap above, and is bolder than the font used later. This is the earliest known example of a dated colour endcap.
