Aaaah, Yes. I still have some (working) Pantone. Before that, we used Magic Markers, with fat little bottles and amazing precision. And, before that, the amazing Flo-Master – an expensive cast aluminium pen with replacable nibs and tins of coloured ink for re-filling the pen. The Flickr comment says ‘mid-60s’. I had my first Flo-Master well before that!

Is that ‘yoken’ as in ‘The act of hit the Gas then Brake in your car’? I had to look up the meaning of the word!

I know what you mean about Rapidographs – and I used to be an expert in keeping them going – but I have more sad then happy memories of them. A friend chucked his full collection into the bin. Then took them out, Then jumped on them. Then put them back in the bin.

Another way of getting a good rendering of the environment was to photocopy photographs of the surrounding and render them in felt pen on tracing with the new foreground design. This could then be copied onto paper and coloured.

All these techniques undoubtedly would have their electronic equivalents, although recent electronic renderings still lack something of the depth of early coloured pencil and yoken renderings which aimed for photo realism.

The best approach is to design the expressive style to suit the medium. So computer artistry will have its own flavour (to borrow Jerry’s chocolate analogy).

If one is a lookout on an arctic convoy in mid-winter, then chocolate is a good food. On all other occasions, it is best not to think about chocolate.
