Copper is a hard to find colour... there are tons of bright green and day glo orange Peugeots here, have seen quite a few red ones, and a number of purple-blue models (a really nice colour) but am thinking copper was about as sedate a colour you could get in a 70's Peugeot and may have not been a big seller.

Did not have anywhere to go today but took trhe Pug out on errands and just loved it... she's pretty fast and rides very smoothly on our less than perfect spring roads and the 27 by 1 1/4 tyres don't hurt either.
