An updated version of a flag I posted in the US State flags thread a little while ago. Made in the same vein as the Maryland state flag, i.e. using the coat of arms of the House of Hanover for Georgia in honor of George II.
Another take on the Cowpens/Fallout flag. An alternate early US or a later Centralized/Unitary American flag. The 13 point star in the middle represents the Union as a whole.
I'm assuming they most likely could, how much they could lump on top of of the 5% and remain competitive is another issue.
To your earlier question, it was the 1783 proposal that provided for state-appointed collectors and also set a 25 year limit on the power. The 1781 version was more open...
If the 1781 Congressional Impost amendment to the Articles of Confederation had somehow been able to overcome Rhode Island's obstinacy and pass, the Confederation Congress would then have had explicit power to collect taxes, if only a 5% duty on imports.
What sort of effects would this have...
Apparently I'm not the only crazy person who had this idea.
(I made this last "year" and it would be for a modern setting, i.e. months Roosevelt, Lincoln, etc.)
