Ralph’s father was a cartoonist and would-be artist who probably instilled his interest early in his son. He had him copy anatomical drawings at an early age. In school Ralph was continually asked to draw and letter things by teachers.
Included here are many different kinds of drawings that were available to copy. Higher resolution copies can be purchased by contacting Ralph at firstname.lastname@example.org.
