Click here for Google street view today (we sure know how to ruin a nice building). Bottom floor left to right I see the following signs/window lettering: The Scenic, Rooms, Idaho Meat Co., Western Nation Bank, United States Depository, Pressary Clothes? (basement level), Meranda The Tailor, Dentist (can't make out the name) and The Ragket Store.
Steunenberg Block can been seen on the left along with the Saratoga Hotel at the intersection of 7th and Main. The train station would be to your right down 7th. Interurban coming at you. ©JTR
