This is an old Formula 3 race car built by Joseph Potts ltd, Lanarkshire, in 1952. They have it in the National Museum of Scotland, where I drew this a couple of weeks ago as a part of Urban Sketchers meetup (as it’s too cold to go outside yet). This is pretty mixed media: pencil, watercolour pencil, white gouache and some acrylic markers. Drawn on spot.
This is just a doodle to play with pens. I get all kinds of pens, new and used, from friends mostly. I don't put these in the sketchbook, it's too intimidating. This is just a little scrap of used paper from drawing practice, 2 ballpoints, and a few neon gelpens
