(ART) The year Mary Henry showed her first painting at an art museum, Adolf Hitler was Time magazine’s Man of the Year (1938). This year the Whidbey Island-based artist will be 94 and she has been a powerhouse of geometric abstraction for almost all of that time, never deviating from her roots in 1920s constructivism. She designed a majestic architectural mural as part of her Howard House show of paintings; if you’re lucky, you’ll catch the grand dame at tonight’s opening.
