Canada #1176a 63c Harbour Porpoise 1988-1991 Wildlife and Architecture Issue, a VFNH Sealed Pack of Inscription Blocks on DF/DF Peterborough Paper, Perf. 13.1, Type 5 Dark Blue DF Card Insert

Sold out

A VFNH sealed pack of inscription blocks of the 63c Harbour Porpoise stamp from the 1988-1991 Wildlife and Architecture Issue, printed on DF/DF Peterborough paper.  The pack contains a DF/LF type 5 dark blue insert card. This type has the new Canada Post logo featuring speeding arrow and plain lettering, with "Philatelic Service" on two lines. This is the scarce perf. 13.1. 

On this issue paper fluorescence has been completely ignored because the perception is that all the stamps are on dull paper. However, this is a bit of an oversimplification, as the pictures of some of the low value stamps will show. While it is true that the coated Slater, Harrison, Rolland and Peterborough papers are generally dull on the face, or non-fluorescent on the face, stamps on Coated Papers Paper are truly "dead" on the face most of the time and are much darker under UV than the stamps on any other paper. On the back, the papers vary from NF which is quite greyish to DF cream to a very light low fluorescence on some of the Harrison papers.
