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...
I'm having trouble identifying this typeface. Any information on its origins would be helpful. Thank you. -Ted
