Artist Gay Bechtelheimer will present the latest in her series of “Art Talks” at the South Arkansas Arts Center. The November lecture will be the first in a two-part exploration of the work of the Post-Impressionist movement, including artists as diverse and well known as Georges Seurat, Paul Cézanne, and Henri de Toulouse Lautrec. The free event will begin with refreshments in the lobby at 6:30 p.m., followed by Bechtelheimer’s onstage presentation.
