Now, these are masks I can get behind (I’m not a big Halloween fan). Block Party owner Mary Levinsky creates beautiful animal masks, and Amber Estes Thieneman photographs them. The longtime collaborators are showing their work in the exhibition “The Mask (Not the Movie).” At the Friday, Oct. 7 opening from 5-10 p.m., reality and the photographic world will intermingle. Block Party will become a forest full of wild animals — or at least models walking around wearing Levinsky’s masks — alongside Thieneman’s photographs of the same.
