We had a Cuba theme in class, and we were to make a poster or similar based on our theme. I had Cuban art during the revolution. I couldn't come up with something smart, so I just made a "montage" with the icons that represented Cuban revolution for me.
The clenched fist of course, 'Viva' as in Viva la revolución, the AK-47 for guerilla warfare, the star and red color for communism and then Fidel and Guevara.
Regular A3 paper and acrylic paint.
Edit: I see now that it would've been better if Fidel switched place with Guevara, as Fidel stood more for the revolution while Guevara was more militant. I guess :3
