Drawing from the live model has a long tradition not only in the history of art, but also the at the Museum. Dating back to 1841, BKM has provided hands-on art education by organizing drawing classes. A century later, Brooklyn Museum Art School opened as a non-degree professional school for artist. This advertising poster produced for the School in 1974 provided a humorous take on the dynamic between artists and models.
