This article explains how to draw Benjamin Franklin as he appears on the US $100 bill.
Draw an oval for his head. Underneath the oval, draw a diagonal line.
Draw a cross on the oval. This will help you draw the face in symmetrically later. Then add a vertical guideline at the bottom of the image. Finally, add a line on either side of the head to help you draw his hair.
Draw two lines to help shape the torso. Add half circles for eyes and begin to add definition to the chin.
Add detail to the eyes and begin to shape the nose. Draw more lines to mark his hair.
Add eyebrows and a mouth. Begin filling in his hair. Add buttons to his shirt.
