The mark consists of a red circle, inside of which is a white circle of about 1/3 radius of the red circle, inside of which is a metallic silver circle of a slightly greater radius than the white circle, the inside of which is hollow but for two blue lines, of a width approximately equal to the radius of the metallic silver circle, intersecting in an "X" with the top and bottom angles acute and right and left angles obtuse. Across the entire circle, covering the portion underneath, is a rectangle of the same color red as the outer circle, bearing the words "AUTO EXPO" in white capital letters, whose length extends slightly past the circle's circumference on both the right and left sides. The red rectangle is set apart from the identical red in the outer circle by a thin white line along the border of the red rectangle and the red circle beneath. Along the top and bottom of the red rectangle are metallic silver lines of a thickness roughly similar to the radius of the metallic silver circle, running the length of the segment of the red rectangle, on top and bottom, equal to the segment between the two points of intersection of the metallic circle and the red rectangle, there being such a segment on the top of the red rectangle and a second on bottom of the red rectangle to form two symmetrical D-shaped metallic semi-circles.
