On the 23rd I rec'd a package which made it to my mailbox on the east coast of the US from France in 7 days.
First up, here's the postage applied - unfortunately not a bunch of pretty stamps.

Inside were some French airmails, issued June 17 2021, celebrating the life and work of Antoine de Saint-Exupéry (1900-1944). The stamps' design is drawn directly from the 1948 airmail semi-postal designed and engraved by Gandon. Sc. CB1 (Y&T PA21).
One sheetlet includes Y&T PA 86,87, and 88. That is shown first below.
Six stamps, all 4 Euros, but in three different colors.

Next is a sheetlet including Y&T PA 89, 90, and 91.
Here we have two at 1.5 Euros, two at 7.50 Euros, and then a significantly larger stamp at 12 Euros. These are covering some international rates. The sheetlet marked with silver and a quote from his 1931 work
Night Flight. My scan below does not do it justice.
This sheetlet came in a relatively limited edition (ed: purchase was through a lottery system), packaged in a nice little folder including a translucent overlay bearing another quote. While I got mine at a reasonable price, I have seen them on
eBay and Delcampe for twice or nearly three times as much. It's a gorgeous souvenir sheet, so very few collectors or dealers will break one up to use the stamps for postage. Decades from now, a used PA 89-91 will probably be worth far more than an intact MNH sheet.

Note re Y&T numbers (and Scott). They are so recent I do not have a catalogue that lists them so I pieced this together from various sources, so I do not know which colors are which numbers in either Scott or Y&T..
A catalogue that shall not be named says these are:
Michel 7933 black violet 4 Euro, 7934 yello green 4 euro, 7935 green blue 4 euro, 7936 olive bistre 1.5 Euro, 7937 olive green 7.50 Euro, and 7938 is the big indigo 12 Euro.
