"Paul Costes (1860-1941)"
Paul Costes, contemporary of Laugé and Henri Martin will never leave Toulouse; the critic Pascal Franck evoked it in these terms "The painter of melancholic evenings, the dreamer in love with the calm and the sad hour when the clouds are glowing with reflections of the sun gone". As for his style, he borrowed from Symbolists and neo-impressionists. This sign is signed lower right in red, and is not dated; it can be given nevertheless circa 1900.
