Denys Ovenden Denys Ovenden Denys Ovenden was born on April 1, 1922. His preoccupation with drawing began very early, since there are drawings on the fly-leaves of books from that period.

His preferred working surface is a "fashion" type board, "CS2 not surface" being the favorite. Reference sources are most important, and Denys uses a body-live, pinned or pickled, to work from, as pinned and set specimens can be misleading due to shrinkage, discoloration or loss of parts. He does use photographs
