This is a fake (in the sense that it is not as old as I initially thought) mapae.

A mapae (馬牌) literally means "Horse badge."

In the Joseon Dynasty, the horse was the fastest means of transportation. So officials (newly appointed governors, Eosa which were governmental spies, envoys to China or to Japan, etc) traveled on Yeokma, which were horses in stations, maintained by the regional governors. The mapae was a badge that showed the rank of the traveler and indicated how many horses he could take.

Now, how do I know this is a fake? Well, this is an actual Joseon drawing of a real Mapae. As you can see, the real mapae lacks any type of writing at the bottom, unlike the mapae /u/Azilmak has here. That made me suspicious, and I checked what it said. I was mildly surprised:

韓國民俗村

Which means, in Hanja,

Korean Folk Village

The Korean Folk Village is (Wikipedia )

a living museum type of tourist attraction in the city of Yongin [...] The purpose of Korean Folk Village is to display elements of traditional Korean life and culture.

So, yeah, it's a fake.

I used The Encyclopedia of Korean Culture (this article ) as the source for the information on the Mapae, which despite its name is chiefly a secondary, rather than tertiary, source (most of its information derives directly from the Annals and the Gyeongguk Daejeon).

I used my knowledge of Hanja to show that it's a fake.
