Last year Greenland Post stopped producing maximum cards. They used to do this for each stamp issue and they also sold the postcards separately. I don't think they were moving enough of them to justify production costs. There were a few postmarks for places in north-east Greenland that I wanted to acquire so I figured maximum cards would be an interesting way to get them. Greenland Post still has lots of postcards available for sale. Of the three stamps I chose, only one was issued after they stopped producing maximum cards. Instead of taking chances on finding postmasters in these remote locations, I had Greenland Post apply the postmarks for me (btw, they charge a handling fee for this). They keep copies of all handstamps used at the post offices in Greenland.
Daneborg station is on the south coast of the Wollaston Foreland peninsula and is home to the SIRIUS patrol: the dog sled patrol operated by the Danish navy. I used a stamp that was issued in 2014 as part of a joint issues with the Ross Dependency. The postcard was used for a previous Greenland SEPAC issue.
About 40 km to the north east of Daneborg is the weather station Danmarkshavn. It is the furthest north non-icebreaker vessels can travel along Greenland's eastern coast. For this card I used the 9 DKK stamp from the Expedition XII stamp issue and the corresponding postcard that was originally used for this stamp's maximum card.
To the south of the Northeast Greenland National Park is Nerlerit Inaat Airport (aka Constable Pynt) which is located about 40km from Ittoqqortoormiit. The airport serves as a transportation hub for expeditions into the park to places like Daneborg station. The postcard I choose was used for the 2014 Aviation III issue showing a Twin Otter but the stamp is from the 2014 Aviation IV issue and features a Dash-8. Not the best postcard for showing off the postmark but I wanted to keep with an aviation theme.
