Hartman Furniture & Carpet Co. used the slogan "Let Hartman Feather Your Nest" in their advertising. They had a large mail order catalog and also had stores in many cities. There is a copy of a 1916 Hartman catalog online here. Another post with a Hartman advertising postcard featuring bride and groom birds is here.
This postcard was mailed from Minneapolis, Minnesota to Lidgerwood, North Dakota. The year in the postmark is unclear, but it looks most like 1910 or 1916. The message:
Dear FolksI thought I wrote last so was waiting for a card from you. Ida was here from Hankinson last week she only stayed one day will write more next time. by by . . .
