It's quite simple over here in Paris. You just take a look at the list of tallest buildings:

Except for the Eiffel Tower that's not a building, but an experimental structure to show off French engineering in 1889, nothing to exceed 100m (300+ ft) dates prior to the late 1960s.
Of course there was no 'pre-war' skyscraper here. Even though France invented Art Deco, local buildings of that style are in the 5-10 stories range.
In a nutshell, Paris had no so called skyline before the 1960s. It was pretty much all mid-rise buildings.
