Hmm, that ticket design definitely looks older than the 1940s. The Oregon Historical Society has a webpage with 1930s tickets, many with the name "Portland Traction Co" on them: https://www.ohs.org/blog/the-art-of...y-passes.cfm
Wikipedia has a table of Oregon railroads, where the start year for Portland Traction Co is 1930: https://en.wikipedia.org/wiki/List_...on_railroads
