VFNH upper left and upper right field stock blocks of 6 of the 39c Canadian Flag stamp from the 1988-1991 Wildlife and Architecture Issue, printed on Peterborough paper that is DF/LF, and perf. 13.6 x 13.1.  The UL block shows a bullet hole in the flag on the LL stamp in the block, as shown, while the UR block shows a "UFO" below the flag on the UL stamp. It is not clear whether these varieties are constant or semi-constant. But they are interesting nonetheless. 

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.
