Question About Tagging Of Canada Scott # 2269ii

Hello,

I recently did buy the Scott # 2269ii Souvenir Sheet on eBay. According to the Unitrade Catalog, the stamp on it is supposed to have pink tagging on all 4 sides. But under my UV Lamp it seems like there is no tagging at all. The picture shows the SS along with the original Scott # 2269 that has the standard green Canada tagging. Have you seen this before, is this a tagging error?

FYI, the SS that I did buy came in its original sealed packing.

Thanks,

Souvenir sheet 2269ii (2269i & France 3437) include pink tagging, the hidden Château Frontenac is not included, the paper is HB with white gum. There is no error on your sheet.

This is what I'm asking, the pink tagging is not there.

The tagging is barely noticeable under the uv light on mine. It's a very light shade of pink with no shine, it looks more like a creamy off-white than pink.
Similar to the two bar tagging of the other stamp on this sheet but much less noticeable.

Thanks
