Title says what I'm looking for. If you don't know the answer but can point me to a good source, I'd be grateful.

I'm trying to see if I can get the number of U.S. States to equal the number of flags (6+19+6 ... and if anybody has a good photo that shows 20 instead of the 19 that I counted, that's good too) shown at Trump's recent Mar-a-Lago speech. Thanks.
