Oak Park artists Tom Burtonwood and Holly Holmes present “Multiplicity,” a new exhibit based on the geometry and patterning they have found in the residential architecture of Oak Park. The exhibit will be shown in the Oak Park Public Library Gallery from July 2 through July 30. This is the first two-person collaborative project between Burtonwood and Holmes since 2008. A reception for the artists will be Sunday, July 15, from 2 to 4 p.m. in the Gallery at the Oak Park Public Library, 834 Lake Street. The exhibit is open during regular library hours. The Library is closed July 4.
