Man, we thought, the ad business really must be tanking if the chairman and chief creative officer of the mega-watt Brownstein Group has just gone and taken up painting. No, no, no, Berny Brownstein assures us, he’s actually been at this for decades, having graduated from the University of the Arts in 1957. The 73-year-old has amassed a large body of work — mostly watercolors and oil paintings — deemed worthy of attention by discerning eyes at the Wexler Gallery, where 20 of his pieces are on display through August 29th. Look for idyllic landscapes observed on his travels, from the Jersey Shore to the wine-soaked hills of Tuscany. Wexlergallery.com.
