Petri Blomquist is an artist who contributed the image "Final Flight of Galileo" to the 2006 Ships of the Line calendar, which appeared as the June image. The image was later reprinted in the Ships of the Line book.
Many years later, working with Gary Kerr, he created the blueprints for the centerfold "Romulan Bird-of-Prey" in the Ships of the Line 2021 calendar.
