Building from the first picture, The Prudential[0], looks pretty much the same right now[1]. I don't know if the actual renovation started already or not but hopefully it'll be turned into this[2].
Edit2: I just remembered there is a movie showing Warsaw in 1935[3] and another one when city was destroyed in 1939[4]. I encourage you to visit Warsaw Rising Museum if you ever have a chance.
