Treacyfaces has both Huxley High and Huxley Low - but I can't tell the difference between them!

Estilo?

Treacyfaces has both Huxley High and Huxley Low - but I can't tell the difference between them!

It's referred to the "waist" (crossbar of E, curve of S, etc.).

So who owns Huxley?

who owns Huxley?

Kingsley/ATF, apparently:

Does that now mean nobody? Not an instance of it, I mean
the idea (even though there would be no US protection for that).

The "idea" of it?! The heirs of Walter Huxley, I suppose?

OK, I guess I'm OK doing my own version. In case
you're wondering what-the-hell-is-he-thinking: the
other day it hit me that it evokes Armenian (thanks
to its basis on the arch shape), and if it was extended
with the Armenian alphabet...

One resultant question: would anybody hazard a
guess as to which version is the most widespread?

There seems to be tons of Huxley's free up for grabs wide across the interwebs. So who knows which cut has become Huxley for the commoner.

The only cut I enjoy is the one with the original capital k - Huxley Vertical D

The only reason I call it the 'original' is because that is one featured in my sample book from '74.
