Peter Langmaid is an avid collector of old racing photos. Attached you'll find two presumably amateur pics he recently sent :
"A couple of photos of old 'chain driven' racing cars. I have no idea as to make or date but location could be France." We must admit that our first thought was Paris-Madrid, yet we have the feeling these photos are older. More like round the turn of the century. Is it Paris-Vienna, or Paris-Rouen perhaps? No too modern for Paris Rouen ( 1894). Our guess - a gutfeel strictly based on car design is 1899 Tour de France. Be sure to check also the spectacular second photo. That car also has different size front and rear wheel. Perhaps you can ID cars #62 and #75 or tell us who the drivers are.
