Kristy Stubbs Gallery has an inventory that would make many museum curators jealous. Works by Pablo Picasso, Edouard Manet, and Henri Matisse, as well as top-notch British contemporary artists, have all seen the inside of the Stubbs space. The gallery focuses on Impressionist, modern, and contemporary artwork across a number of media. Exhibitions, from Laura Wilson’s Western-themed photographs in “Pictures: Still and Moving” to the English-inspired works of Elaine Ferguson’s “London Calling,” are occasionally organized to display larger collections of work from artists represented by the gallery.
