The card was sent to Mrs. Sarah Malone in Punxsutawney in 1909.
The message reads:

Dear Sister Why don't you write

I don't know much about Sarah Malone, except that she was born about 1851 and was married to James Malone, who is listed as a farmer in the US census.
It really is Groundhog Day today, so if you want to find out more about the tradition or watch the live webcast of Phil, you can take your own virtual trip to Punxsutawney here.
