A late 19th Hand-Made American Flag with 13 Six-Pointed Stars forming an Even Larger Six-pointed Star of David
Six pointed stars on American Flags are a very rare trait, shared only by a handful of known examples. The same can be said of flags with cantons arranged in a six-pointed great star configuration. This configuration of stars on a flag of pieced and sewn construction is known on less than four or five surviving flags. The pattern is very similar to the star pattern seen on the official Great Seal of the United States. The first die of the Great Seal, cast from brass in 1792, featured a “glory” of six pointed stars arranged to form a single six pointed star. Although the “glory” on the Great Seal is oriented to with a single star at the top, the “glory” pattern on this flag is rotated 90 degrees.
