A pen, ink, brush, and gouache drawing of a mini-bike creep. It was on bristol paper before a computer screen.
FW India ink, hunt 102 crow quill, w&n series 7 brush, I think a Gillot 303 ef nib, and gouache (for reverse).
NOTE: The post-uploading compression used by this site for display images does not like two color drawings, so please excuse the bad aliasing. The original is quite large and in a lossless bitmap format.
