Thanks Sir F.A. Rien for these informations.

In fact, these stamps are not really Cinderellas.

My opinion is that Cinderellas are often advertising labels. While these
Test Stamps are connected to Post Stamps because they serve to adjust and to
test the postal purposes, without destroying real Postal Stamps.
They are rather classified in "Back of the Book", such as Tax Stamps,
Precancelled Stamps or Training Stamps ......

For the interested people, there is a Wikipedia page on this subject =

Best regards.

And sorry for my approximative or very bad english .... If you want to
correct my errors of language, it should be very fun for me.

What catalogues do I use ?
Usually classed as Cinderellas, I don't think there's a full
'catalogue' of them.
