Interesting French Cinderella Stamp.

Could you please share your knowledges about this French Cinderella stamp ?
Can this be considered more to be a label not a stamp,because it is imperforated. There is also a cancel, but I can't tell were the stamp was used. The only thing visible is the date and the yare which I tink is 1861.

IMO, this is a "cinderella", a grouping which also includes "labels". It is not a "stamp" as it had no postal value or specific postal application/usage.

Whether it is perforated or imperforate has no bearing on its classification as a "cinderella".

Have you tried Google Image as an identification tool?

From just the French words on this label, "patented French postal paper" is mentioned along the sides of the inscription. At the top of course is the name of a company (which I could not find by googling), and Poitiers is a city in France. But I can't offer any insight beyond what is seen on the stamp itself.

A pure guess is that the A Pinchot company placed this label on packages of the paper or on shipping crates/boxes of the paper.

Thank you both for the information. I have tried to searched it with Google Image tool but unfortunately I couldn't find anything. The label is not in very good condition,but the cancel guide me that it was applied on a cover from this period.
shermae,
The translation you have made is very useful for me . I must say that my knowledges at French language are poor ,but the words "patented French postal paper" are raising more questions than answers. It is interesting why would someone use this inscription on his advertising label. Could the companies mentioned on the label were suppliers of a paper for a some French institution ?
The image printed on it has a figure which holds scales . Isn't these associated with the juridical system?

Just googled it. Looks like A Pichot was a printer or publisher based in Poitiers. This book crops up a lot - and if correct that would explain why this label makes a big deal of the paper being used.

Great work Ringo , you have managed to solve this puzzle.
I will look at link you have posted .

Your cinderella depicts "The Law"
And the text says "Trademark. The Law punishes the counterfeiter"

Thank you for the clarification, vayolene.
The additional translation of the inscription you have made is very helpful. This will make the resolving of
this interesting question a easier task.

There is a nother information about the company in the Law section of a 1850 book. It says that the company is also desling with insolvency cases.
