Heading west on Carretera Central (the extension of Marta Abreu), you'll reach a series of comic book–style murals with a tongue-in-cheek look at Cuban-American relations as the predominant theme. Glimpse such scenes as the Statue of Liberty being made off with by Cuban helicopters and an unsavory-looking man draped in the stars-and-stripes shouting 'terroristas!' at Cuban guerillas while himself concealing a bomb. Even in this era of improved relations between the nations, they've not been wiped.
Easily incorporated into a walk to the Che monument, the pictures are just before the intermunicipal bus station.
