I used the challenge template, moving the circle and adding a triangle to portray the iconic sphere and cone. The colors are very typical of the late 1930's 'streamline' style. I kept it simple in keeping with the graphic art of the period. Papers are K. Pertiet's Classic Embossed Grid #1 (brown paper darkened for sphere & cone); K. Periet's Basic Paper Scrolls #1.
