Steve, here is what I have for you. The Oil on canvas by Nicol. There is no records as to who the artist is. I did find sales results for paintings similar to yours signed Nicol for $200.00.
The water color is by: Pierre Eugène CAMBIER (1914-2001),
Pierre Eugene Cambier brilliantly captured French cityscapes, waterways, and countrysides in his watercolor paintings. Cambier first began to publicly exhibit his artwork at the Salon des Independents in Paris in 1948. His work was included in the annual Salon d’Automne exhibition between 1953 and 1960 and later on at the Galerie Urban in Paris, the Galerie O’Hara in London, and the Galerie Sothman in Amsterdam.
Cambier continued to work and paint in Paris, where he also taught drawing and illustration to budding artists, until his death in 2000. Cambier’s masterful depiction of Paris***** *****ght, color, and architecture continues to attract collectors to this day. His works are exhibited in collections around the world. Cambier’s legacy also lives on through his daughter, artist Daniele Cambier, who creates lively, naturalistically rendered French scenes in watercolor.
Unfortunately his watercolors sell for: &5.00 to $250.00.
