Before continuing the coverage of the downtown area, I'm going to head back to the Pearl District to add a couple of newly found signs. It's always a nice surprise to discover a new sign on a building you've seen hundreds of times before.
I can only make out a small portion of this from street level. "B.T Co..." is all I can see. It's on the west-facing side of Powell's Technical Bookstore and you can see it from NW 9th and Couch.
