Hello, I randomly picked a cover from a stack I have here and this was the one. Travel. How appropriate, although I do not know the aircraft type 🙂

Issued in 1978 as part of the Inuit series, the second issue in fact. I was quite surprised to see the catalogue value of these. Issued over 35 years ago and they only have a value “Used” of 40p per stamp (GBP). MUH are catalogued at 30p per stamp. Wow! better off using as postage eh!

But how often do I say there is no value on old Mint stamps unless for postage.

Anyway, nice to have a copy on the cover with the commemorative post mark.

Enjoy your stamps..

Best wishes.. Michael
