When the 7 train emerges from the underground to become elevated as its travels through Queens, it passes through a succession of stations in one of the most ethnically diverse areas of the city. The renovation of this line included a major work of art that pays homage to the borough of Queens and its diversity. Artist Yumi Heo designed 30 faceted-glass panels for the stations' mezzanines and platforms. Collectively titled “Q is for Queens,” the panels use each letter of the alphabet (e.g. A is for Aqueduct racetrack ... Z is for Zoo) to highlight neighborhood places and events, in a narrative that brings the richness of Queens to life, filtered through the artist's sensibility. 33rd Street-Rawson Street includes the letters A through J and two other murals, including one of a "Redbird" subway car and one depicting a typical storefront in Flushing. 40 Street–Lowery Street includes the letters K through P. 46 Street–Bliss Street includes the letters Q through Z and two other murals, including one of a typical neighborhood scene in Flushing, illustrating the cultural diversity of the neighborhood and of the White Stone Bridge that links the Borough of Queens to the Bronx.

Yumi Heo (1964-2016) was an illustrator and author of more than thirty picture books. Born in Korea in 1964, she grew up in several rural villages due to her father’s military assignments. She was a graduate of San Ji University and the New York School of Visual Arts. In 1989, Heo moved to New York and earned an MFA in Illustration at the New York School of Visual Arts. Heo illustrated several folktales and picture books by other authors, such as “Sometimes I’m Bombaloo” by Rachel Vail, as well as “Henry’s First-Moon Birthday” and “Polka Dot Penguin Pottery” by Leonore Look. Yumi wrote several of her own picture books, including “One Afternoon,” “Ten Days and Nine Nights: An Adoption Story,” “Father’s Rubber Shoes,” and “Lady Hahn and Her Seven Friends.”
