Our good friends over at PidgiWiki have managed to obtain high resolution (5000x6000!) versions today of the SM12 Comic Eclipse artwork. You can see Mitsuhiro Arita his work in full detail! These consist of the Cosmic Eclipse pack artworks of Arceus, Dialga and Palkia, Blastoise and Piplup, Solgaleo and Lunala and Togepi, Cleffa and Igglybuff. These will also be used for playmats in the future at Play! Pokémon events.
If you want to download these images uncompressed in full resolution please visit their website, I have linked the pages down below. And please give them some love over at Twitter @PidgiWiki! 😄
