This paper considers the studio in art therapy as a neglected yet key aspect of the field's history. Descriptions of studio art practice among the founders of the American Art Therapy Association and such predecessors as Mary Huntoon were obtained through historical research. Because both art therapy and art studios are hybrid in nature, the author proposes that ideas from fields outside of art therapy be utilized for the rich intersections of knowledge and wisdom they may bring to art therapy studio practice. Studios in the history of art therapy are discussed as providing a locus of intersections and thus of possibility. (Contains 2 figures and 1 editor's note.)
