That is an AWSOME video, a TRUE CRAFTSMAN at work!
And I thought hand craftsmanship was long dead, just like REAL graphic designers, you know the guys who use to draw all their graphics using Rapidograph pens & ink, using Letraset lettering for display type.
Now days everybody with a computer and some free drawing software is a designer.
Below are photos of me working as a graphics designer at Texas Instruments in the 80's before I had a computer, I created the ET logo on illustration board using pen & ink and type was set using a Varityper typesetter.
I can't say I miss cleaning those pens....
