Fifty-Two United States.
i do like the current flags of D.C. and P.R., but nevertheless decided to make these ones, just for fun.
they are based on the coa's of George Washington and of Puerto Rico, respectively, and on the common feature of many American flags: reflecting the number of different entities by stars or other items. in this timeline both were admitted to the Union at the same time, that's why both flags feature 52 stars.
a distinctive element is the number of red stripes: two for DC and three for PR.
the real flag of PR is based on the flag of Cuba, where "[t]he three blue stripes represent the three departments in which Cuba was divided at that time" [wikip']
i've also rearranged the flag of USA.
'cause 52 = 4 × 13.
two different variants provided.
1] there exists also a version
of the Washington's coa with colours reversed [wikip'
2] "the star [on the flag of Cuba] was the new state that should be added to the United States."
3] "Douglass Commonwealth"? why "Douglass"? ["Confusion over the state of Washington and the city of Washington, D.C. led to renaming proposals during the statehood process for Washington in 1889, including David Dudley Field II's suggestion to name the new state "Tacoma." These proposals failed to garner support. Washington, D.C.'s own statehood movement in the 21st century includes a proposal to use the name "State of Washington, Douglass Commonwealth", which would conflict with the current state of Washington. To distinguish it from the national capital, Washington may be referred to as "Washington state", or, in more formal contexts, as "the State of Washington". Residents of Washington (known as "Washingtonians") and the Pacific Northwest simply refer to the state as "Washington", and the nation's capital "Washington, D.C.", "the other Washington", or simply "D.C.".", wikip'
