Drawing "Ballet" Paris Opera 1948

I fell in love with this charcoal drawing! Remarkably produced in 1948 by the french artist monique lancelot, it is a pas de 2 in costume, sketched from life, between the first principal dancer of the paris opera lycette d'arsonval and the first star dancer alexandre kalioujny for the zadig ballet choreographed by serge lifar... On paper, handwritten signature, numbered 8 and titled in the margin, marie louise cardboard, under glass, blond wood frame, hanging system... A unique and unique piece rare ! Good condition. H: 35 / 54.5 cm l: 27.5 / 40.5 cm d: 1 cm.
