Stanley, Jean and Thomas.
This is not very good the sun was too strong but you can see what the(y) look like this was taken in
This Cyko postcard was used from 1904 to 1920. I will guess that it was taken right around 1914.
Thanks for stopping by, do come again:)
Update from Iggy:
Washougal, Washington (state) is just upstream on the Columbia River from Portland, Oregon. It was incorporated in 1908.
