1920 Dorothy MN U91 Envelope Cover DPO Dead Post Office

This is a 1920 postal envelope cover from Dorothy, Minnesota to the A.H. Eilers & Co. publishers of St. Louis, MO. The cover is slightly yellowed, and it may be the "buff" colored cover, and not white. The cover was cut along the top edge with some slight tearing on the edge. It is also somewhat water stained in the top left corner. Dorothy, MN post office was in service from 1898 to 1908 and again from 1920-1945 and is now collected as a Discontinued or Dead Post Office. The cover will be shipped in a poly sleeve in a regular envelope with some light card stock for protection.
