The Voltigeur avion is the kind of toy that every kid would love. At least I would. The description translates (by machine) to:

An original activity for the aces of the stunt-flying! It is enough to fix the steel wire rope (10 m) between 2 trees and it left! Small and even larger will hustle themselves to be the first to split the air. Very drink some and simple to go up.

Imagine being the first kid to “split the air.”
