The poster of Fortunato Depero is the best one.
It's about time I learned Italian because I've got a book about the Futurists in Italian and I can't understand it. "Il Futuristi; La Storia, Gli Artisti, Le Opere", published by Guinti in 2004. Not sure if it's a catalogue or a monogram on the movement. Great, full colour reproductions of paintings, puppets, posters and other graphics, a real delight. I think Depero might be my favourite of their artists; real simple, effective style.
