Stephen Scott is painting from inside the Subaru, above my sketchbook in this photo. Pencil, Carbon fountain pen, and watercolour in 5 ¾ × 8 ¾″ Stillman & Birn Gamma (150 gsm) ivory sketchbook.
This March, 1990, sketch was done on location with a blue, felt-tip pen of some sort, on paper that’s clearly full of acid given how much it’s yellowed (probably generic typing or note paper). Probably a Pilot Fineliner. Measures about 6 ½ × 2 ½″.
