In general, the influence of Anglo patrons has been much less pronounced on Hispanic arts than on American Indian arts. The Hispanic crafts revival was confined to a much shorter period of time, beginning in the early 1920's, reaching its peak in the late 1930's, and dying down by the Second World War, less than 20 years. During this period, in spite of the enthusiasm of the wealthy Anglo patrons in northern New Mexico, Hispanic crafts never "caught on" nationally in the way American Indian crafts did. Interest was fairly well limited to the Southwest and Southern California, the areas in which the adobe hacienda revival was taking place. The major interest in Hispanic crafts was as furnishings for these comfortable Southwestern-style adobe homes. These crafts were not, as were American Indian crafts viewed as valuable art objects in themselves purchased with an eye for speculation. Hispanic arts to, a great degree have been ignored by the speculative Anglo art market. A beneficial consequence of this oversight is that the artisans have been freer to work according to their own standards and within their own traditions. Their work has not been "emptied of previous vital meanings" and become a meaningless revival. as has so much ethnic art of this day. Rather it has remained as an object of cultural pride and identity and not simply the product of the tastes and demands of the art market
