Prosimians - Show Your Lemur, Galago, Potto And Other Prosimians On Stamps

In page 6 of this thread I posted the 1988 WWF set of Madagascar shows different prosimians.

The stamps were reissued in sheet without WWF logo on October 9, 1992 to publicize the national stamp exhibition "ANTANANARIVO '92", held in Antananarivo, Madagascar and the world post day celebrated in that day.

In the above post, I posted my last item in my Prosimian stamp collection. I believe that all my stamps and items are represented in this thread. I will continue to update this thread when I have new stamps and items in my collection. Please, feel free to add your stamps and items to this thread. Thanks.

An old page from nature book printed in Leipzig in 1896 shows etchings of prosimians like galago, loris, tarsier and lemur:

I just added to my collection a great cover sent from Laos to England franked with a stamp shows the Tarsius spectrum. It is very rare to see real commercial covers from Laos franked with Lao stamps issued between 1980-1999 (mostly printed in Cuba):

Philippine Tarsier (Tarsius syrichta), stamps issued in 1969 on a commercial cover sent to Israel:

LEMUR

Hoping to see many lemurs on my first visit to Madagascar next month... in the meantime, here's some on stamps!

Coquerel's Sifaka Lemur (Propithecus coquereli). Grenada, 2019.

I see that Laophil started this thread with Madagascar Scott #C60, the Ring-tailed Lemur (Lemur catta) stamp designed and engraved by Pierre Gandon, so this is a bit of a late addition... but here are a pair of artist's signed die proofs in black and violet-brown respectively (hopefully the scans show the colors adequately):



He also included a few nice plate proofs (trial color essays), so I will just add this one different one:


And finally, a maximum card for the issue (which I already posted over at the maximum card thread, but thought I'd throw it on here as well):

This is a good place, I think, to show this interesting error. I don't believe it's listed in any of the major catalogues. Madagascar (Malagasy Republic) Scott #C90 (Y&T #PA 106) was already posted earlier on this thread, but here is an inverted overprint variety, with a normal version of the stamp shown first for comparison.

(Incidentally, the Indri shown in the last post is now classified as Indri indri, the specific epithet "brevicaudatus" is a junior synonym.)

Potto (Perodicticus potto) and tarsier (Tarsius spectrum), St Tome and Principe, 2009.
