Here are more Northern Pacific poster stamps, labeled series 5. If series 1 and 2 were issued in 1915 and series 3 and 4 in 1916, then this series may have been issued in 1917. I’ve found a series 6 and a series 7 but no series higher than that and I doubt NP issued any poster stamps after the Great War.

This set of stamps shows scenes along the St. Croix River, which forms part of the boundary between Minnesota and Wisconsin. Stamp number 5, as shown above, is the 1902 Northern Pacific train station in Taylor’s Falls (now Taylors Falls), MN, which is across the river from St. Croix, WI. The station still exists as a community center, though it is not so rustic looking and the shelter shown on the stamp at the near end of the station has been torn down.

Series 4 was of scenes in Minnesota’s Itasca State Park. Series 6 featured Montana and Northwest scenery including Mount Rainier and the Oregon Coast. Series 7 was all Oregon and Washington scenery.

Great Northern also had several “see America first” series of poster stamps. Sets featured scenes in Glacier Park, Blackfeet Indian paintings by Joseph Scheuerle, and Charles Russell paintings. The Great Northern Pacific Steamship company also had at least one set of stamps.

All of the complete stamp sets I’ve seen have borders on the two sides and bottoms but the tops just have perforations. These perforations may indicate that a blank border was detached, but more likely some other stamps (possibly another set of the same series) were once connected to these.

As with yesterday’s stamps, I scanned these at 600 dpi instead of the usual 300 dpi. Unfortunately, making them into a PDF still loses some of that resolution so I’ve offered the option of downloading the original 19.6-MB JPG scan of the stamps.
