"Nicolette and Sophie have been instrumental in helping build up my poster collection over the last 20 yrs with skill and expertise coupled with charm and reliability. Together they are a “class act” helping to fill the walls of my country home with French and Swiss posters which have considerably increased in value and given my family never ending pleasure. My best posters from the 1920s/30s combine striking design with atmosphere, colour and nostalgia for a by-gone age."
