PH: Spell the Word S-N-O-W With Postcards

Let's spell the word S-N-O-W with the pictures of a postcard.

Example:
S - snow, South Carolina, etc.
N - North Dakota, night view, etc.
O - owl, Oregon, ocean, etc.
W - water, Washington, etc.

Send the 4 blank 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). Sender's choice.
