Adolphe Braun House Rosa Bonheur's Deer, c. 1895. Three (3) charcoal prints (variations in hue). Medium format: 78 x 59 cm with margins. The charcoal process with shade variations was used by Braun from the 1870s to reproduce works of art, particularly paintings. It is clear that the use of uniform pigments was a palliative to the impossibility of retranscribing original colors. The prints thus produced are perfect examples of the creativity that lies behind this work of pictorial inventory.
