Wouldn't it be neat to be rich? You could put together a first-rate art collection overnight -- ten years or so in the art world. That's what Connecticut collector Virginia Vogel Mattern did. In 1988 she became enraptured with pottery from the pueblos of New Mexico, and over the next decade sought out the best pieces available. Then, needing to downsize in 2003, she donated it all to the Denver Art Museum. Nancy Blomberg, the DAM's Native Arts curator, selected over 100 of the best pieces from the gift to make up Breaking the Mold: The Virginia Vogel Mattern Collection of Contemporary Native American Art. The show, which is still open, is a marvelous way to get a thorough introduction to the field.
