A woman from Austria's Tourism Office sent me a google map with the location notated. Praise the Google! Here is a Google street view from a spot 100 feet forward of the 1959 image. Almost 60 years later, it looks like most of the neon is gone.

this is Vienna, standing on Akademiestrasse/Kärntner-Ring, looking roughly north (Wollzeile).
The "Moulin Rouge" on the right is now closed.

I think this may be Vienna, Austria. For starters "Österreichische Volkspartei" means "Austrian People's Party". Secondly a search of "Akademiestraße" which is on the sign under the streetlight appears to be in Vienna.

My guess would be Vienna. The Österreichische Volkspartei (Austrian People's Party) is headquartered in the Austrian capital, as well as Semperit (manufacturer of rubber and plastic products). The Neuer Kurier (a Viennese newspaper) was first published in 1954. Also, the W on the license plate of the motorbike in the lower left would indicate Wien (Vienna).
