A young cyclist poses with his bicycle in this vintage real photo postcard. The studio photograph shows the young man wearing the uniform of his bike club (V.C.K.). His bike clothing looks comfortable and clearly facilitates easier riding. Compare his clothing to the cumbersome bicycle clothing seen in photographs of woman of this era. Women clearly had to sacrifice comfort for beauty and modesty. I believe that this RPPC is of French origin. The logo of the publishing company of the postcard paper has a logo showing a horse and horseshoe (see image or reverse).
THE CABINET CARD GALLERY 
The horse’s head within a horseshoe was the logo of the Guilleminot company, a manufacturer of photographic plates and paper.
