Aspen-based collector Kimiko Powers and her late husband, John, were connoisseurs of the old school. They were broad in their interests; as a result, they amassed some of the finest art works of art available. Ron Otsuka, the esteemed curator of Asian art at the Denver Art Museum, made friends with the couple over thirty years ago, and he convinced them to put their collection of more than 300 Japanese masterworks on long-term loan with the DAM. Some of these pieces make up Japanese Art From the Colorado Collection of Kimiko and John Powers, and while many may look modern, they are actually hundreds of years old. This show is the best of the trio that inaugurated the DAM's new wing -- and it's open for a few more months.
