There is a cat + tea-based art collection being sold by the shop below:
You can use a middleman service to place an order for the prints, the site says they are hand-signed by the artists. For the record, I can only go by what it says on the site and based on the images and the text: 作者直筆サイン入り, I have to assume it will actually be signed by the artist and not just printed on. If you just like the art and don’t care for the autograph, the tea bag set is a good option.
The Pokemon artists featured are the following:
Atsuko Nishida
Best know for designing Charmander, Squirtle, Bulbasaur, Charizard, Pikachu and half the Eeveelutions. A resume that places her as arguably one of the greatest character designers in all of human history,
A Game Freak employee who was responsible for a lot of character design and I see her as a modern “Ken Suigmori” when it comes to drawing stock character art (see below example for what I mean)

My Mizutani came a couple of days ago. It was a separate order because at first I didn’t love the art but then I realised not getting only one seemed foolish.
