I found this postcard at the Charleston Antique Mall in Vegas.
The postcard was addressed to Mrs. Harriet Rum, 212 Elm St., Northampton, Mass. The writing is hard to read, but I have done my best to transcribe it:
May 14, 1911

I can't seem to find anything about Mrs. Harriet Rum, and I can't read the last name of the author. If you can read her last name, please let me know and I will see what I can find.
