Big excitement, Saturday at 9:15 a.m., in Marquise, avenue Ferber, which is just a section of the National Road Boulogne-Calais.
One saw at the place called "Le Champ d'Asile"... a flying saucer. It was, in fact, an optical illusion.
The fog hid the post that lifted the white disc of a newly installed billboard. The consoles - furnished with insulators - of a pylon of the P.T.T. [phone] line, completed the illusion, by topping the disc.
Fortunately, two brave young girls soon discovered the mistake made by some wild imaginations.
