I just started building this bike. Does any one know why it says, "Prix de Cannes" on the top tube. I thought it is specific to this bike, but I read somewhere else that another Mercier had that on the top tube.

I has a "crown" with Mercier engraved below it. This is located on the fork crown.

Vitus Rear Drop outs, Serial number is on the bottom of the BB, I don't have it on hand though.

Just interested in what model it is and maybe what year? Also it was built with Columbus Tubing.

Thanks!
