Unknown Stamp From France

Hey! I have recently come across a stamp that I haven't been able to identify. I've attached an image of it below. I know the following based on my research.

* It is of French origin
*It displays the logo of the French postal service from 1960-1978
*It says Republique Francaise rather than France, which I believe dates at or before 1975

If anyone could help me find the stamp in a catalog or even just the year of its issue, I would be vastly appreciative.

Thanks!

It's a cut-out from an aerogramme. Yvert 1003-AER.

It is a cutout from an aerogramme, basically postal stationary so unlisted in Scott. Yvert lists it under 'entiers postaux' as 1003-AER, issued 1970-1975.

Thank you so much for your help! It took me quite awhile just to get the info I did. I'm very grateful for your knowledge. Have a blessed day!
