Nick Cardi (Nicholas Viscardi) was an American comics artist best known for his DC Comics work on Aquaman, the Teen Titans and other major characters. Cardy was inducted into the Will Eisner Comic Book Hall of Fame in 2005. Cardy entered the comics field working for the Eisner/Iger studio, joining circa 1940, he worked on Fight Comics, Jungle Comics, Kaanga Comics, and Wings for Fiction House Publications. He wrote and drew the four-page backup feature "Lady Luck" in Will Eisner's 16-page, Spirit Section, from the May 18, 1941 strip through February 22, 1942. In 1950, Cardy began his decades-long association with DC Comics, starting with the comic book Gang Busters, developing his breakout reputation with Tomahawk, his most prominent series at the time. From 1962–1968, he drew the first 39 issues of Aquaman, whose character had previously starred in a backup feature in Adventure Comics, and all its covers through the final issue (#56, April 1971). Cardy first drew the Teen Titans in The Brave and the Bold #60 (July 1965), wherein the superhero sidekicks Robin, Kid Flash, and Aqualad were joined by Wonder Woman's younger sister Wonder Girl in her first appearance. After next being featured in Showcase #59 (Dec. 1965), the team was spun off into their own series with Teen Titans #1 (Feb. 1966). From 1966–73, Cardy penciled or inked – sometimes both – all 43 issues of the series. Cardy left the comics industry in the mid-1970's for the more lucrative field of commercial art. There, under the name Nick Cardi, he did magazine art and ad illustrations, including movie advertising art (though not necessarily the "one-sheet" posters) for films including The Street Fighter (1974), The Night They Robbed Big Bertha's (1975), Neil Simon's California Suite (1978), Stanley Donen's Movie Movie (1978), Martin Ritt's Casey's Shadow (1978), and Francis Ford Coppola's Apocalypse Now (1979).
