* United States flag changing

Page 2 has a brief yet very significant report on the creation of the United States flag, headed: "Star Spangled Banner" and including: "The flag of the United States is to be altered--The stripes are to be reduced permanently to their original number of thirteen; but the stars are to be constantly increased in number equal to the number of the states in the Union..." with a bit more (see photos).
Complete in 4 page, a little water staining, otherwise good.
