Though Mike Carroll’s Schoolhouse Gallery is one of the more prominent showcases of art in Provincetown, he has always been an extraordinarily talented painter in his own right. For this Provincetown 400 year, he has joined the Berta Walker Gallery’s roster of artists, and his work is part of the current exhibit at the gallery, which is on view through September 5th. Also part of this exhibit are shows of work by Paul Resika and Sky Power. The gallery, at 208 Bradford St. in Provincetown, is open by appointment (go to calendly.com/bertawalker) on Wednesday through Saturday from noon to 4 p.m.
