Marquez is best known for "Nard n' Pat," a comic series showcasing his eccentric characters and quirky storytelling, published through the alternative press in the 1980s. Beyond this signature work, he contributed to underground anthologies and small-press titles, and he pursued self-publishing projects that kept him firmly rooted in the independent comics scene rather than mainstream publishing.
Though he never achieved wide commercial fame, Marquez is appreciated by connoisseurs of independent comics for his strong draftsmanship, inventive creature designs, and commitment to personal, uncompromised storytelling. His career embodies the DIY ethos of the underground era, and his fantasy-influenced art continues to attract admirers among collectors and devoted fans of alternative American comics, securing his place as a unique and enduring voice in the medium.
