Restoration of a fashion print

Restoration of a belle époque fashion print, in the
style of Paul César Helleu.

A restoration project of an early 20th-Century print, in the style of French artist Paul César Helleu.

The print was signed by a certain G. Bardou. Unfortunately, to this day, I haven’t been able to find more information about the artist.

On the picture below, on the before side, you can see the print was heavily marked by oxidation, as well as dirt and tears. These have been mended and reduced.
