The motorcycle plate indicates the "Bouches du Rhône" French department (Marseille CA2).

The car is most probably a "Chenard & Walcker" AIGLE8 (used a FORD V8 engine ca1935), rather a luxury car. Front plate not visible on the picture. Strange since stricly mandatory in France even at that time.

Difficult to be more specific : there are "restaurants de la poste" in many, many French cities !

Two used to be very famous : Saulieu and Avallon. Saulieu at that time deserved three Michelin stars. A family lunch at such a fancy place would have certainly deserved a photo...

i was wondered if someone would notice that ... follow my next photo i'll post ...

Thank you, Wayne Johnson, for describing your careful observation. My responses:
Shadows can have shiny pools of light in them?
Shadows can look like reflections: everywhere or only in France?

[I agree with Wayne Johnson. The heavy jpeg compression of the image as submitted obscures much detail in the original photo, but we can still see that the middle leg-like object is indeed a leg as there remains evidence of the lighter-colored spat or legging, here in shadow. There's no sign of that on the left "object." What appears to be a reflection in the left "object" - in reality a shadow of the woman's dress - may also well be a scratch or white speck on the surface of the print, like the one on the door of the car, which is similarly blurred by the jpeg compression. - tterrace]

The leg on the right (her left leg) is in the sun, the leg on the left is in the shade, and what appears to be a third leg is the shadow of her skirt. The sunlight passing though a gap in the pleat of the skirt is a bright spot on the shadow that looks remarkably like a reflection off a shoe.

She looks like she was quite a formidable woman. I wouldn't want to ask her if she has thee legs.

The white-haired old lady appears to have three legs, each with a different shoe. I know French people sometimes seem strange, but this is ridiculous.
