Registered cover from Cuba

Republic of Cuba is one of those countries which prints too many stamps for collectors and sells them mostly as CTO (cancelled to order), but when you send real mail, most of mail is shipped without any cancellation. I was partially lucky with this registered cover, because it is cancelled, but on wrong side! You can see cancellation on second picture bellow.

Stamps on cover:
The 40th Anniversary of Diplomatic Relations with Burundi, Cameroon, Gabon, Senegal, Uganda, Liberia and Madagascar, issued on 2.9.2014.
Kangaroo, from set Endangered Wildlife, issued on 15.11.2017.

My friend Wolfgang visited Cuba with ship Berlin, which postmark you can see bellow hand cancellation. Thank you so much, Wolfgang!
