I want to know the answer to the following question:
Which 1907 piece did Picasso present in the show that introduced Cubism to the USA?
All the background I'm provided with is that "In the Armory show Pablo Picasso exhibited La Femme au pot de moutarde (1910), the sculpture Head of a Woman (Fernande) (1909–10), Les Arbres (1907) amongst other cubist works.". Is that enough to answer the question?
Answer: yes
