PH: Color of a Flag #2

Thanks to @user6937 for the idea for this swap.

The flag for this swap is the USA flag which has three colours, red, white, and blue.

Send your partner three postcards - the main subject of one will be red (eg. firetruck, cardinal, etc.) one will be white (eg. polar bear, snow scene, etc) and one will be blue (eg. water, bluebird, etc).

Please send the 3 postcards 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 your thinking in choosing which cards you've sent.
