USSR, 25 October, 1988 (Zagorsky 5934)
The Nuclear-powered icebreaker
Sibir on a high-latitude expedition. This stamp is great because it's got people doing science, a boat, a helicopter, a map with route, and plenty of ice.

The ship was the 2nd such-named Soviet icebreaker, in service from 1977 to 1992.

A new
Sibir is scheduled to enter service in 2020. Here it is under construction.

Interestingly, the first
Sibir (1938-1973) was first named
I. Stalin but that changed shortly after the death of Stalin, the same fate as pretty much anything named after the not-so-dearly beloved Papa Joe.
