Are Postal Labels Cinderellas?

I also have a small section for these but do not actively collect them.
However, they are not 'Tabs'. They are gutters, the inscriptive kind.

Of course if the terminology in Canada differs, then I apologize as I know that it does all over the world and sometimes it's hard to keep up !

Nice thread, would be nice to get some scans going to see what is out there.

I should add that I only save the gutter in my Cindy album, not the stamps !

Ah, there's the rub, Mr. Bus. I considered a page in the cindy album for tabs, as you call them (Scott's calls them labels). I was wondering about showing the accompanying stamp if I had it (even detached as many seem to be) but I don't think I would consider separating the example I showed on the first page of this thread.
Or perhaps the detached tab/label could have a label of it's own simply describing the stamp it came with.
Ah, decisions, decisions!

As promised I put the question of whether this kind of sheet-centre vignette would be accepted as a Cinderella entry to two experienced English philatelic judges.

Both replied that they would accept it as a suitable cinderella entry, irrespective of whether they were displayed with or without se-tenant stamps attached.
