Mr. Costantino has continually developed his distinguished practice during defined eras of work with a versatility of media, techniques, and styles of illustration from graphite pencil to color pencil to watercolor to pen & ink. Inspired by historical drawing precedents from which much of his work derives, he has attained comparable artistic levels of illustration, while interpreting the varied designs of his client’s distinctive projects. Mr. Costantino is indebted to these clients – mentors for encouraging superior standards of imaging architecture and his many assistants over the decades, who have helped bring each of these illustrations to fruition.
