Description

FIG. 1 is a front elevational view of sheet material with the periodic circle of the elements showing my new design, the undisclosed rear being flat and plain and is understood to be of no substantial thickness;

FIG. 2 is an enlarged fragmentary view of a portion of the central area shown in FIG. 1 for clarity of disclosure; and,

FIG. 3 is an enlarged fragmentary view of one of the circular elements shown in FIG. 1 for clarity of disclosure.
