Today’s card features the frontier between France and Italy near Menton. It’s a popular postcard subject, perhaps because of its proximity to Mediterranean resorts where international tourism first flourished. Frontiers are artificial constructs superimposed on the planetary surface continuity with mapping pens and straight edges. Ants, birds and bees can pass unhindered but human traffic is constrained and regulated. This border crossing, high on the rock-face overlooking the sea is largely unchanged according to Street View. The border guards have departed and traffic passes freely, courtesy of the Schengen Agreement. Checks were still in place at the time of this card. A chauffeur poses next to his limousine, his passengers seated in the back, their luggage stacked on the roof. It could be a storyboard for a cinematic life of Raymond Roussel, forever crossing frontiers with his devoted mother in a limo with the curtains drawn to exclude the world outside.
