The message on the back reads:
Picture taken in the wilds of Lewis County. Notice the dog. I can get a separate picture of him very lovely looking.
Have you seen Aunt Hattie lately. I am contemplating taking the G.N. train which goes through Rainier and thought I would let them know.
Leon
While we don't know who the people in the picture are, I am fairly certain that the card's recipient was Cora E. Shea, born in about 1870 in Illinois. She and her husband, James Shea, lived in Portland with their three children Leo, John, and Margaret. I wonder if the son, Leo, sent this card to his mother. Leo would have been 26 at the time. Although the Census records show the name as Leo, I guess it's possible that his full name was Leon.
