Hi Trodent...
You are referring to the stamp called "
Humber River Canyon" which is
Dark violet, but
Scott 139...But my stamp is called just "
Humber River" which is a
Scott 134 which is identified as
BROWN VIOLETThe stamp you are referring to is Scott 131 in N.S.S.C. Catalouge...Which is a 10 cent stamp.

Unitrade shows Scott 134 as a BROWN VIOLET as shown below..

Now the 2002 N.S.S.C. catalogue shows the "Humber River"
4 cent stamp as N.S.S.C. 129 as shown below.

NOW, the new N.S.S.C. catalouge identifies this ""Humber River" stamp as N.S.S.C. 126 and is colour BROWN VIOLET". as shown below...

So, unless I am loosing my mind, I DO NOT see any reference to the Scott 134 having the colour VIOLET.
