Last Thanksgiving, my mother-in-law gave my 5-year-old niece a little green ink pad and she started creating unique masterpieces based on her thumbprint while waiting for the turkey to appear. Unfortunately, some of these still decorate our dining room walls. New York-based artist Merle Temkin presents a much more sophisticated take in Fingerprints, a self-portrait exhibit that opens today at the Cultural Center. Slowdown has the details.
