Ché imagery is everywhere -- and I mean everywhere -- in Cuba. It's almost all part of the revolutionary canonization of the man, who is the revolutions' martyr. The thing is, the Ché imagery is all government propaganda. It's rare to see Cubans voluntarily displaying it.
(American flags, on the other hand, are constantly displayed in various forms by Cubans -- I'll do another point on that in the near future.)
My son Kenny took this picture at something like 3am in Havana.
