Sam de la Rosa had his first comic book credit appear in DC Comics' Action Comics #534. He provided finished art over layouts by Keith Pollard for Green Lantern #160 and then became the regular finishing artist starting on World's Finest #285, with layouts by Silver-Age Great, Rich Buckler. That same year, Sam caught the attention of Marvel Comics when Bob Layton and Mark Gruenwald asked him to finish a few pages of (Bob's) layouts on Hercules Prince of Power Mini Series, Issue #4 in 1982. His work on Hercules led to years of regular jobs for Marvel providing inks and finished art on various Spider-Man titles, Venom Lethal Protector, Venom Separation Anxiety, Captain America, Black Panther, Squadron Supreme, Iron Man, What-If, Dr. Strange, Daredevil, The Thing, Spider Woman, Indiana Jones, Star Wars, and many more. On Marvel’s Epic line Sam was fortunate to ink over pencils by Alan Weiss/Val Mayerik on Steel Grip Starkey, and Jim Starlin personally selected Sam to ink several hundred of his Dreadstar pages. Returning to DC Comics, he inked All Star Squadron, Captain Atom, 22 issues of Firestorm and DC’s last two Star Trek Annuals, in 1995. Sam worked for Dark Horse on the very first Predator comic (1989), Disney Comics’ Roger Rabbit, First Comics’ Sable and The Badger, Eclipse Comics inking over Eric Shanower and Sam Kieth, Acclaim Comics inking the great Dick Giordano on Sliders, Red Circle-Archie Publications embellishing over Spider-Man co-creator Steve Ditko, Malibu Comics, Ocean Comics’ Popeye, Noble Comics’ Justice Machine, Comico Comics inking Elementals over future Eisner Award Winner Bill Willingham, Lone Star Comics, Antarctic Press on their flagship title Areala Warrior Nun, Image Comics on Supreme and Vanguard, Fleetway/Quality inking about 100 Covers primarily on Judge Dredd, and still other companies. His work continues to be published by many comic book companies in various Omnibus, TPBs, Hardcover Editions/Collections, DVDs, and a sampling at Marvel.com. Prior to his pro comic book work, Sam was a prolific contributor of art to comic book fanzines starting in 1969 with The San Antonio Comics Club Bulletin. He attempted to put together a fanzine, SUPER ONE in 1972 but for various reasons it was not to be. Finally in 1977 he designed/layed out, provided art, secured art contributions, hand pasted-up the pages, and finally published NIMBUS 3. In the mid 1970s he was a freelance artist doing editorial cartoons for his college newspaper, drew art professionally for other publications and also operated a manual sign printing press for a large Department Store. In the late 1970s up to 1982 Sam was an "Illustrator" working on government projects at San Antonio's Lackland Military Base for Impact Productions. Impact was co-owned by his great friend and mentor, Pat Boyette and Fred Himes, who were both artists/writers/painters for Charlton Comics. Sam left steady employment in 1982 upon receiving regular work from both DC Comics and Marvel Comics and never looked back!
