For Spring: A bicycle ride in Paris, circa 1900.

The Paris policeman asks:  "What's going on here !!"

To which the people in the crowd say:  "But Officer, we are admiring the pneumatic tires on this bicycle by  Kosmos.  They are marvelous !!"

The poster, by artist Louis Oury for the tire company Le Kosmos (affiliated with Dunlap), was printed in Paris around 1900.   Click on the image and enjoy the detail -- the women's dresses, the policeman's face, and all the hats.

Happy Meteorological Spring, which began yesterday (March 1).  Get outside and ride your bike.
