The Tribune photo, dated July 21, 1984, has the following caption on the back: "Pitts stunt plane performs inverted flat spin." The handwritten notation on the back expands on the Trib caption "Bob Oliver, Danville, in his Pitts stunt plane does an inverted flat spin. Few airplanes can recover from this maneuver." The biplane, which has painted geometric stripes radiating from fuselage to tips of the elevators and wings, is shown at the top of a plume of smoke designed to enhance the view of ground spectators.
