(written from a Production point of view)
Dan Day is a Canadian comic book artist and brother to David and Gene Day. He broke into the industry in the early 1980s, shortly after his brother's death, and by 1986 had become the primary artist on the Cases of Sherlock Holmes series from Renegade Press. Other titles he worked on include Detective Comics, Doctor Strange, Elvira, and Captain America.
His only Star Trek credits are cover art with Dick Giordano on issue #7 "Pon Farr" in DC Comics' first Original Series volume and #7 in Malibu Comics' DS9 series "Working Vacation" (with his brother David).
