I got some images this morning from a friend in Cuba with details of the events in Havana for the 500th anniversary. Some of these will overlap with the Partagas event.
Quite a bit going on. The big public event on Saturday the 16th, and probably the place to be, is a concert by Los Van Van on the Malecon by the Piragua, that's the space between the Hotel Nacional and the Maine Monument, basically in front of the Gato Tuerto.
Anyway, here are the images.
