This postcard features a drawing of Duluth, Superior and the St. Louis River, and was copyrighted by Thomas W. Wahl of Wahl Realty Co. in 1908.

Perhaps you’ve seen this image in poster form? The text on the back of the postcard explains:

A half tone of this beautiful “Birds Eye View” 28×42 in. sent prepaid upon receipt of 50c.

This is a reproduction of a hand drawing made from the latest government map. The detail is minute and is topographically correct.

Wahl Realty Co.
Second Floor, Lonsdale Bldg.
Duluth, Minn.

The finer details aren’t clear on a postcard, but below are a few attempts to zoom in.
