Here's the back of the card.
Nellie sent this card to Harry in Redfield, New York in 1909 with a message that reads:
Going to Mexico Thur. with Jones. Just got back from Selkirk. I been out on the river nearly every day. Nellie
We will be home Fri on the ten o'clock train.
If you're wondering how Nellie could be in Scotland and then go to Mexico on Thursday and be home on the train on Friday, it's because she was referring to Selkirk and Mexico, New York. Her entire trip was about 150 miles.
