A VFNH matched set of plate 2 blocks of 10 of the 5c violet blue stamp from the 1967 Canadian Free Press Issue, printed on the scarcer fluorescent paper and non-fluorescent papers. The lower left block is on LF-fl paper, while the other three are on the NF paper that is very close to dead on the fluorescence scale, appearing a dull violet colour under UV light.
Unitrade values these at $77, counting them as blocks of 4, plus singles. The blocks all grade between 75 and 80.
