In his first graphic novel, It's a Good Life, if You Don't Weaken–one of the best-selling D+Q titles ever—Seth pays homage to the wit and sophistication of the old-fashioned magazine cartoon. While trying to understand his dissatisfaction with the present, Seth discovers the life and work of Kalo, a forgotten New Yorker cartoonist from the 1940s. But his obsession blinds him to the needs of his lover and the quiet desperation of his family. Wry self-reflection and moody colours characterize Seth's style in this tale about learning lessons from nostalgia. His playful and sophisticated experiment with memoir provoked a furious debate among cartoon historians and archivists about the existence of Kalo, and prompted a Details feature about Seth's "hoax".
