Any help appreciated tracking down the script used at bottom and left of Duchamp's Obligations Pour La Roulette from the 1920s. It's unfortunately either overlapping or cropped, which makes it challenging... See the full poster here: http://www.christies.com/lotfinder/prints-multiples/marcel-duchamp-oblig...
Thanks!

Font or calligraphy?
If it's a font in the 1920's there are only a few fancy ones in metal type.
To assist in identifying letters I tinkered with the image in the link to attempt to improve the signal to noise ratio in the green letters.
Still confusing.
