Kim Jungsuk studied Western painting as an undergraduate and art education in graduate school. With over 100 illustrated books to his credit, he holds solo exhibitions, creates murals, teaches picture book workshops, and curates picture book exhibitions. He wanted Bread, Bread, What Kind of Bread? to feel as warm as fresh-baked bread, so he had fun cutting and pasting various papers like bread wrappers, notebook paper, manu paper, and colored paper. His picture books include It’s Good to Come Outside, It’s Good to Draw, and Pop Goes the Fruit!, as well as the essay collection Even Though I Can’t Draw Well.​
