Before Marzipan Physics began wheatpasting her work throughout New York City, she was an extraterrestrial particle physicist from the planet Eupraxia. Um, let me rephrase. Before the Lower East Side-based street artist adopted the deliciously cosmic pseudonym as her own, she’d given it to the lead character in a comic she published in 2015. Drawing upon Japanese manga, Archie Comics, mid-century sci-fi, and ’70s glam rock, Marzipan (the artist, not her creation) developed a style and a protagonist that proved equally at home on the page, the canvas, and the walls of the city.
