I want to know the answer to the following question:
Which Metzinger piece was hung in La Maison Cubiste?
All the background I'm provided with is that "At the 1912 Salon d'Automne an architectural installation was exhibited that quickly became known as Maison Cubiste (Cubist House), signed Raymond Duchamp-Villon and André Mare along with a group of collaborators.". Is that enough to answer the question?
Answer: no
