PH: Independence Day Scavenger Hunt (USA/Canada)#4

Thanks to @shirleyinCA for this scavenger hunt idea.

You will send your partner three (3) postcards in an envelope that somehow depicts the theme of America from the choices listed below:

•historical
•a president
•national monument
•Washington
•USA map (USA map or state map)
•USA flag (USA flag or state flag)
•fireworks
•eagle
•Mount Rushmore
•Statue of Liberty
•US military
•Alamo
•St. Louis Gateway Arch
•Sender's choice (for this you could even think a bit outside the box - what's more American than baseball, rock & roll or a Norman Rockwell painting?)

Please send in an envelope. Postcards should be unwritten and unstamped. They should be store bought only and of good quality. (No handmade/freebie/ad/zazzle). Let your partner know which pc represents which topic.
