Galerie Hertz is displaying three artists in its spring exhibition, presenting each as a solo show. Don Buckler’s “Hommage to Mapplethorpe” are paintings that reference Robert Mapplethorpe’s flower photographs. “Reflections,” by former Louisvillian Emily Church, features abstractions of landscapes such as bodies of water. Ceramicist Lena Wolek is walking in the footsteps of her Russian grandmother in “Who Stole Our Heroes?” by making bogatyr (“hero” in English) teapots.
