Eau de Roche
Rochas

Eau de Roche is a traditional Eau de Cologne, juicy citruses, breath of civet, gentle flowers then poof, gone. Very nice.
According to another website released in 1946 created by Marcel Rochas himself, which sounds improbable as he was a fashion designer, reworked as Eau de Rochas by Nicolas Mamounas in 1970. I don't remember smelling that one but it sounds like a different composition altogether.
