If you go to Card Shark site, he has two decks with this back.
The Gypsy deck in this teaser shows the back and a playing card French pip deck.
On his site there is a pdf you can download with every image of his LS Medieval--but this is his pdf and it's legally licensed from Lo Scarabeo. You have to find his site and download from there--the above link is a good start.
That is the red and gold backs with the leaves look like Card Shark's deck backs to me. If I am wrong, sorry, but that so very very similar to the deck I have.
I don't know if anyone has posted a close-up of their Card Shark Medieval deck with backs.
Best,
