Born in 1926, McGinnis has spent over 70 years of his life creating book covers for almost every genre, movie posters, magazine illustrations, portraits, etc., and has worked almost exclusively in Tempera paints.
He started with covers for characters Mike Shane, Perry Mason, and Carter Brown, then grew into spy thrillers, like James Bond, and eventually entered the romance genre.
It was a logical choice, as McGinnis had a talent for depicting the feminine form in a most erotic fashion (as well as males). He started in gothic romances and then soon became the first bodice ripper illustrator when Avon published Kathleen E. Woodiwiss. The he worked famously creating covers for Johanna Lindsey, as well as Patricia Hagan and other authors.
