Hey Idaho, Washington, Oregon, and Utah collectors...
 

...where the heck is this?
Two billboard signs are readable. One is Pearlo Dental Gum.
The only references to that gum I found are in the
*1907 Lewiston Evening Teller (70+ ads), and a few ads in the
*1907 Oregon Journal
*1907 Salt Lake papers, and one in the
*1910 Tacoma Times.
The other sign says Pacific Engineering Co.
The only references I located are in the
*1908-09 Oregonian (the company had Portland offices)
*1912 Salem, Oregon newpaper
*1909-21 Hawaii papers (where the company was founded), and
*1908 Aberdeen, Washington.
Any ideas or photo references on the location or player?

Hello bbpostcards, This looks like Bellingham ballpark, have you checked images for the Bellingham Gillnetters or Bellingham Chinooks? B-ham ballpark had houses right on top of it like this image, but I can't find a good image of the grandstand.... I can tell you it's not Electric Park in Aberdeen, any of the Tacoma Bowls, or any field in central Washington (Yakima, Wenatchee, Walla Walla, etc..) Best of luck and as always great stuff!

Great idea. I hadn't considered Bellingham. Thanks, I'll follow it up.
