This is a drawing of an open source photograph of the London Museum of Natural History. To make this drawing, I sized the photo to fit on my computer monitor and carefully measured the position and angle of every object in the scene using a K&E graphic divider. I transferred these measurements to a sheet of Bristol 14" x 17" paper and drew the entire image first in pencil and drew over the pencil freehand in ink.
The original drawing is a 14″x17″ hand-drawn pen and ink drawing, drawn using a .25 mm Rapidograph pen and black India ink. Prints are printed on matte archival quality acid-free paper.
