Bazar Nadar / Wouter Lambrechts This artist study was made by the Italian photographer and painter Gaudenzio Marconi. The studio props were used in several photographs by Marconi. He sold many images to the école des beaux-arts in Paris. Also Auguste Rodin had examples of Marconi's nude studies in his archive. Marconi left Paris in the 1870s due to the Franco-Prussian wars. Records show Marconi was working in Brussels since then. [Claudia Cavatora, 2008]
This example is used by an artist who drew white guide lines on the photograph and pasted it on the cover of a sketchbook.
