Tower Liquor! That's the Foshay Tower in the logo. It's right across the street.
The House of Vision had a fine sign as well, and it makes you lament again the end of the age of metal neon signage; in the wintertime, when the sun fell early and fast, downtown lit up with names and shapes and colors, and every block was different. It hasn't been like that for years, and few note the loss.
As you can see, it's the Doctor's Buildling here. I don't know what it was before the overhaul. It might not even have had a name.
