PROCESS ;
Calotype, also called talbotype, early photographic technique invented by William Henry Fox Talbot of Great Britain in the 1830s. In this technique, a sheet of paper coated with silver chloride was exposed to light in a camera obscura; those areas hit by light became dark in tone, yielding a negative image.
The Spanish Republican government commissioned Picasso to create a large mural for the Spanish display at the Paris International Exposition at the 1937 World's Fair in Paris.
