From Pole to Pole

Sometime in December I got a sepac book of vouchers for gratis stamps and discounts from various participating countries. Using the codes I sent e-mails to Greenland, Guernsey and Jersey. On Thursday my free souvenir sheet from Greenland arrived. Let's see when/if the others arrive as well. ^___^

This is the souvenir sheet:

From Pole to Pole (issued 20-10-2014)
It is a joint issue with the Ross Dependency.

Thank You very much Greenland Post!

In my collection I also have three of the stamps from the Ross Dependency. Anyone can help me to get the missing two?

Thank You very much Sharon!
