This was posted on reddit and it looks legit from the holo. The language used is the Malay language native to Malaysia and Indonesia but here in Malaysia, the cards given at theaters were English so that got me thinking, is this a legit Indonesian card?
Edit : tagging @quuador for this.
First time I’m seeing it. Will start investigating and sending out some messages right away, to see if anyone knows anything more about its legitimacy.

There are multiple pictures on google images for it, both Twitter and Instagram, kinda cool
Just did some google image search and found two. It is indeed from Indonesia. The promo number indicated it is the first Indonesian promo card, possibly even the first Indonesian Pokemon card.
Awesome, thanks a lot for these pictures. I’ve contacted someone who has this Pikachu, and he’s going to try and locate a second copy this weekend to sell to me. 
I also asked him about information in general, like if there are any other (upcoming) promos or sets, so will let you know if he responses anything useful to those questions.
Cool to see another language pop up after the Thai cards. I just wished they were a little closer to home, haha.

Pokémon is really stepping up their international game! Love it!
Thanks for sharing!
EDIT: Do they have English or Japanese backs?
Nice, it’s a shame that cards like this will be likely impossible to get on ebay
Very cool too see it’s the first promo
Can you see if they can track down a third copy as well?

I guess it’s a long shot but I would be interested in a copy as well
