Unlike the first Interior Valley Competition, the second was open to all participants. It also featured the inclusion of sculptures and drawings in addition to the sole medium of painting that the fist contest exhibited. The new rules resulted in nearly 600 applications with 150 drawings and about 50 sculptures.
