Just got these beauties in the mail--completing my Newfoundland collection. Simply sharing--hope no one minds me showing off....
The first one is C2c, VF, LH. The variety (the c) is without comma, the "A" or "AIR" is under the "a" of "Trans". It is one of 400 issued by Newfoundland in 1919 (as depicted on the stamp)
The other one is C3j, VF and NH... Its variety is with 1 +1/2 mm between "AIR" and "MAIL" and the "1" of "1921" is below the "f" of "Halifax". Only 556 were issued.
Lots of history about these variants and quite interesting how they came to be.
I've now completed all the C2 and C3 variants. whew!
