Sketchbook in hand, Paul Olson walks the Arboretum’s less traveled paths observing and reflecting on the diversity of life and the passing of time. A teacher in the Illustration Departments of both MassArt and Rhode Island School of Design, Olson has created illustrations and paintings in varied subjects over the years. All the work in this new exhibition—from quick sketches to larger drawings and paintings—were completed in the landscape of the Arnold Arboretum. The opening reception will take place Saturday, January 19, from 1 – 3:30. The exhibit will run through March 24, and an artist’s talk will be given on February 21 from 7 – 8:30 pm.
