This is at 415 Penn ave, I can't seem to find the 400 block of Penn downtown though. Is it possible that this is where the Gateway Center is now?
Yes it is possible, in fact that's exactly where this was. I actually just tagged the exact same view in 1917 (the corner of Penn and Evans looking west), see here: http://retrographer.org/photos/2092 for a link to a map.
