LGPE - Pokémon Festa 2019 (Korea): Shiny Pikachu and Shiny Eevee

[theSLAYER]

Pokémon Festa 2019 has been announced for South Korea!
Duration of the Festa was announced to be from May 3rd, 2019 to May 12th, at the Starfield Hanam Store, Coex Mall.

While no event distribution has been officially announced, it's important to note that various pop-up stores in South Korea traditionally had a local wireless or infrared distribution running alongside the physical pop-up store.

Along that note, this image was posted on the official site.

If I'm not mistaken, the text roughly translates to:

Quote

[Pokémon Let's Go! Pikachu & Eevee] can be experienced here.
If you clear the missions given during the experience, you have the opportunity to receive certain souvenirs, limited to a first come, first serve basis.

Perhaps these souvenirs are serial codes that can be redeemed on Let's Go!?
Only time can tell. If any new details were to show up, it'll be added to this thread (by others) or post (by me)

Edit: The main site has been updated! The translation is a bit wonky, but if I'm not mistaken:
Purchasing the games there will give you a serial code!
Let's Go Pikachu redeems Shiny Eevee, Let's Go Eevee redeems Shiny Pikachu.
edit: infosheet on other page conflicts the one below.

(other info sheet, note how the Let's Go image above Pikachu/Eevee are swapped)

Spoiler

Additionally, on a different official site, there's also an image stating the amount of serial codes you get, depending on what bundle you purchase, as well as the promotion period to get the serial codes.

It's apparently either for purchasing a copy, or showing a purchased copy, or showing a recently purchased copy. Still pending proper translations.
Showing either Let's Go Pikachu, Let's Go Eevee or the Pokéball Plus awards you 1 serial code.
Showing either one of the Let's Go Bundle with Pokéball Plus awards you 2 serial codes.
Showing a Nintendo Switch bundle with either Let's Go Pikachu or Let's Go Eevee awards you 2 serial codes.

Promotion runs between May 3rd to 12th, 2019, between 11am to 7pm.

@BLACKBIRD @katsuya @wraith89 I need your language expertise here, to confirm if it's limited to new buyers or showing old copies work as well.
