McGuire's parents allowed her to explore and discover this world. But when it came to art, they didn’t want her to turn out like them—broke! Even though they exposed her to art, the only formal training they would let her have was a sign-painting course in community college. As a result, she defiantly ran away with the proverbial circus by joining a rock band. For 20 years McGuire got lost on the open road, and then found herself in southern Louisiana with a paintbrush in her hand. Inspired by the mystery and history of New Orleans—she sunk her brush into sign painting—pairing local folklore with the music and mystique of the Crescent City.
One of the best examples of McGuire's work is for American Horror Story Season IV “Freak Show.” The original circus acts that inspired the show inspire her, and she strives to bring dignity to them as people, not just showcase them as performers. This balance of humanity and creativity is what she's after—as she directs the “art department” of the carnival that is her life, not to experience it herself, but to convey the sense of nostalgia, excitement and wonder that the big top brings. You could call it a desire to create ritual and suspense. Her art is hearing and passing down stories. She's a documentarian and circus banners are her canvas.
