Randy Ploog pointed out Manierre Dawson's 1910 triptych "Prognostic," which at first glance may seem like abstract art but, as Ploog noted, also includes several elements of engineering graphics and symbols common to Dawson's trade. "Prognostic" was painted at least a year and a half before Europe's first great abstractionist, Vassily Kandinsky, painted his earliest abstract work.
