Asserted "Flag of the Whiskey Rebellion"
Additional info: See The Whiskey Flags, An intoxicating look into a sobering subject (written by Richard R Gideon &amp; published by the North American Vexillological Association). In this article Gideon references flag expert Anthony A. Martin's article in the National Flag Foundation's (NFF) 'The Standard Bearer' magazine "Martin points out that no contemporary accounts mention this flag." and quotes Martin: Several facts support my theory that the Scenery Hill flag was, at best, a relatively minor Whiskey Rebellion flag, and most likely designed and produced post-rebellion. and goes on to say "Martin makes several points to support his theory, but his major point - that if one assumes this flag was a rebel flag then the symbolism is wrong - cannot be easily dismissed." Gideon goes on to strongly theorize that the flag is probably a Federal Army flag and not a flag of the Rebellion.Instead of a 1790s era origin, this flag may have been made during the 100th anniversary years of the Revolution, when numerous 13 star flags were made and flown as part of the commemoration. In 1794, there were 15 states in the Union, not 13. 
Historicity claims:

Flags of the World- This flag comes from the coloring book "Flags to Color, Washington to Lincoln," and is found on page 3. It's listed as "Whiskey Rebellion, 1794."
