In an effort to advance visual literacy (VL) education, the purpose of this paper is to develop and test a VL instruction program for 2.5-4-year-old children in a public library setting. The study was designed as a series of VL workshops for young public library visitors. Each workshop collected information about children’s existing VL knowledge, introduced them to new visual concepts, and measured their engagement and comprehension of the newly acquired material. The study data were collected via questionnaires and observations.
