You're right, it is very difficult to find adverts of this kind; I was lucky to grab that one at eBay but the seller didn't mention the source in detail (just "from a 1967 publication"). The reverse shows a small part of an advert with the letters "arch" so it might have been a magazine targeted at architects. I take it as 0.001mm (which is equivalent to 0.2%) but I have problems to rate that claim, mainly because I don't know the details of the manufacturing process and the dimensional stability of polymer leads. I'm happy to hear that I was able to gazump you ;-) I'll soon try it with another advert from 1968 :-) I am eager to see what your blog will show in a week or two! Kiwi-d, thank you for your comments.

Magazine, newspaper, catalogue...? How did you find it? One question - where was this advert published? Magazine, newspaper, catalogue…? How did you find it?

It seems surprisingly difficult to find adverts from the very early days of 0.5mm. The 1/1000 claim is interesting. That would be +/-0.0005mm, or pehaps they meant to 0.001mm or perhaps even they meant 1/1000th of an inch considering the US is non-metric. Personally I find all those claims a bit hard to believe for something as variable as a stick of graphite. Still, who knows? Ahhhhh, you have gazumped me again! See my blog in a week or two and you will know why :-) Excellent posting.
