Many of the 72 Extras were designed to form continuous linking borders. Combinations of these geometric forms can provide endless variations of decorative elements in the style of Frank Lloyd Wright. Many of these images were based on Mr Wright's "Saguaro Forms and Cactus Flowers" illustration for an unused Liberty magazine cover of 1926. Other imagery in this set was derived from assorted geometric designs by Wright.
