There is no known sketch of a Hopkinson flag—either U.S. or naval—in existence today. However, he incorporated elements of the two flags he designed in his rough sketches of the Great Seal of the United States and his design for the Admiralty Board Seal. The rough sketch of his second Great Seal proposal has 7 white stripes and 6 red stripes. The impression of Hopkinson's Admiralty Board Seal has a chevron with 7 red stripes and 6 white stripes. The Great Seal reflects Hopkinson's design for a governmental flag and the Admiralty Board Seal reflects Hopkinson's design for a naval flag. The predominance of red stripes made the naval flag more visible against the sky on a ship at sea. Both flags were intended to have 13 stripes. Because the original stars used in the Great Seal had six points, Hopkinson's U.S. flag might also have intended the use of 6-pointed stars. This is bolstered by his original sketch for the Great Seal that featured a U.S. flag with six-pointed asterisks for stars.
