In 1777 the Continental Congress replaced the British symbols of the Grand Union flag with a new design featuring 13 white stars in a circle on a field of blue and 13 red and white stripes - one for each state. Although it is not certain, this flag may have been made by Philadelphia seamstress Betsy Ross, who was an official flag maker for the Pennsylvania Navy. The number of stars increased as the new states entered the Union, but the number of stripes stopped at 15 and was later returned to 13.
To celebrate Flag Week and as a build up to the 4th of July, I chose to create a Gallery Glass interpretation of an oil painting by Childe Hassam, (1859-1935), Allies Day, May 1917. I found the line drawing in a Dover book entitled Color Your own American Paintings by Marty Nobile, which features line drawings of 30 American masterpieces. ISPN 10: 0486445267.
