I have dragged this typewriter around for more than 50 years. I found it in an antique store when I was in college. It's still fully useable, except that it's REALLY hard to find ribbons. Basically, it's just another object to dust. But it is a beautifully made object. The basic shapes and perspective were blocked in with a 2H pencil, then I used a Sakura 005 micron pen to do the contour drawing.
New one shadowed & ready for color. Drawn with a Pilot Custom 823 FA (favorite pen at the moment) with Noodlers 41 Brown on Strathmore Mixed Media paper.
This started as a pen line drawing (with Skura Pigma micron pen) which I then painted with Dr PH Martin's Hydrus watercolors. They are fun and very bright. This is on Strathmore 300 11x17 Bristol paper.
