It is a charity label for the benefit of the mutual insurance of the postal workers. It is well possible that it also covered their children or orphans. I suppose the overprints were for the branches of the insurance organisations in the former colonies or for the workers in the post offices abroad. The price (20 F) corresponds roughly to a letter fee in the post-war time. Such an amount seems quite normal for a charity contribution.
I got this back from a friend of a friend:
Yes, it's a "cinderella". You could buy those "cinderellas" at the many post offices in France. Some ones went into albums for collectors, but most of them have been burnt or thrown to the bin. The buyers gave money for the "oeuvres mutualistes des PTT"; in return, they received one (or more) cinderella(s)". The cinderella was a mean of control: the postman coul not receive money without giving cinderella.
Hello, this isn't so much a question on its identity, but more to find out how it was used. I have seen an example where it is used alongside a postage stamp on a cover and I have seen mention of helping the orphans. They were from the first few years after the war ended and the L'AIR PUR almost hints at the wicked number of TB cases in Europe during that period. Was it a charitable addition to the regular postage? I have seen them online with Morocco and Algeria overprints.
Thanks, Danny
p.s. It's hard not to be impressed by the engraving skill of the designer or artist.
