- N.Z. 5/- 1898 Mt. Cook stamp diagonal lines CTO
What was the story NZ 1898 Pictorials with corner diagonal line CTO?
I recall it is noted somewhere these diagonal lines were CTOs for some purpose - can someone remind for what purpose please?
Bought this superb 5/- 1898 Mt. Cook stamp SG 259, decades back and forget the story! (Stock 542AX)
Were they done in London or in NZ?
Thanks in Advance.
