She is till so far not on a stamp, only on an Arctic cover from Greenland.
The cancellation on this cover is from the DISKO built in 1968, only a hand cancel gives the ships name DISKO, but the ship depict in the logo is not the DISKO, which vessel is depict with the logo GREENLAND ARCTIC SUPPLY GRØNLANDS FORSYNINGEN 1972 I do not known, have seen the logo on other covers with other ships names.
First I was thinking that she was a DAN vessel of the Danish company of Lauritzen, but not any vessel in that fleet around 1972 is the same as the vessel in the logo.
Also I have not any info on this Greenland Arctic Supply, who has more info?
