A good question. I am aware that Mixte frame sets are becoming more sought after but cannot understand why. This is hardly a problem since I have several Mixte bicycles including two Peugeots (one of which is the touring model with fenders, lights, racks etc), a Sekine, a Raleigh Gran Prix, a Sekine, a Le Circuit, a Le Jeune and who knows what else is back there in The Old Shed.

Again, the question is why are they so popular?
