Believe it or not, I now have some information about these buildings. I wasted a federal holiday to look up the permits. I hate microfilm- it makes me motion sick. Anyway, drumroll please:
6659-61 N. Clark
Permit Date: Dec. 13, 1922
Owner: J.J. Rosen
Architect: B. Leo Steif
Contractor: J.J. Erickson
(Note: I've gone back and added some of this information to previous posts)
Useful, isn't it? Just for fun, I counted up how many more corner buildings I need to complete this project. 31 more. I have 13. At least I have something to work on over the winter.
