The artist Emilio Lobato, mostly famous for his mixed-media abstract paintings, is also an accomplished printmaker. This is not surprising when you learn that his mentor was printmaster Mary Chenoweth, with whom he studied while he was a student at Colorado College. For Printmaker's Portfolio, Lobato assembled a group of abstract prints that surveyed his career, dating back to the early 1990s. The small but strong show was mounted on the mezzanine loft at Havu, where it was a little crowded, but that was a minor complaint.
