As with his other homes, Brown filled this house and garden with collected objects—well over 1,500 in total by the time he bequeathed the estate to SAIC—referred to in scholarly material as his La Conchita Collection. The breadth of objects included was comparable to his other collections, with everything from formal paintings to African objects to everyday objects. However the La Conchita collection can be seen to reflect his California environment, featuring an extensive array of nearly 500 ceramic objects featuring objects by amateurs, regional factory-made wares, and Mexican wares by families or studios. The contents and direction of this collection was guided both by Brown's own exploration of the environment and by the network of friends and colleagues he established in California, namely his friend Lisa Cathcart, Director of Casa Dolores, Center for the Study of the Popular Arts of Mexico.
