In Japan, this card was released as a SM-P Promotional cards, and is one of the five cards made as part of a collaboration between The Pokémon Company and the "Munch: A Retrospective" exhibition present at the Tokyo Metropolitan Art Museum between October 27, 2018 and January 20, 2019. The illustration draws inspiration from Edvard Munch's The Scream, the 1910 version (tempera on cardboard) of which was displayed in Japan for the first time as part of the exhibition. Mimikyu was available in the Pikachu/Eevee Scream Mini Card File, which could be purchased from the shop present at the exhibition and the Pokémon Center Online starting October 27, 2018.
When all five of the Munch collaboration cards are placed in collection number order, the Pokémon from the preceding card is featured as a silhouette in the background of the illustration — Pikachu is visible in the background of this card. The sequence continues on Rowlet.
The Scream attack is another reference to the basis of the card's inspiration. This card's Pokédex entry comes from Pokémon Moon.
