The block, as illustrated by Nancy Cabot (whose real name was Loretta Leitner Rising), debuted on January 20, 1937. Variations of the design darken or lighten the corner triangles. The sun disc in the center can sometimes delineate the pie-like sections of the 8 triangles in some manner (Beyer p. 294-12), or simply begin with an undivided octagon (Beyer, p. 294-11).

The color combination above is adapted from Self Portrait Wearing a Scarf dated 1911, by the Russian artist Zinaida Serebriakova (1884-1967), herself shining forth through the innocence of a young face. Full of enthusiasm it would seem, though with sleep still in the eyes beginning a new day, she delights in painting the gorgeous fabric she is wearing. Serebriakova was still active in the 1960's and even in this portrait there is a sense of durability, suggesting a long and productive life to come.
