Missing Part Of The Tagging.

Missing part of the tagging is it common? Thank you.

Hello adanak44, welcome!

I haven't seen many of these at all myself.

The tagging could be over-doaked (hours in water?) or have been mis-printed as such.

Do you have a scan of the back while fluoresced? The stamp I mean!

I can't imagine that it would be a result of too much soaking. That tagging is just as permanent as the ink used to print the design - the paper would fall apart well before the ink would ever soak off. Since it's a souvenir sheet, too much soaking would just cause the perforations to fall apart. I'd say it's an interesting tagging flaw. Congratulations on finding it, I look through all of my modern Canadian stamps with UV light in the chance of finding something, but it's a rare occurrence when something does show up.

Thank you very much for all the inputs. I did check adminware however didn't find anything to match and say anything about this kind of
errror. Will upload the full cover later. Thanks again.

I would contact City Stamp Montreal. They will likely know the answer and provide an estimate of value.

Here is the full cover image,

be something got spilled on the stamp. I note the the obliteration covers he stamp on the lower left corner and it too obscure the tagging, so may be a similar liquid caused the same result?
