A little over 5 years ago I was able to obtain a nice folded letter that I posted here.
https://goscf.com/t/57739&whichpage=27I was going through the Westpex offerings and found another piece of the correspondence so I had to have it


The strip I believe is 68 - 69 -70L

And a 3c Type I Scott 11?

And the back stamps

This was mailed 1 week prior than the one I obtained a few years back.
Does anyone know if there is a census of these Garnier letters?
