So I spent a few hours going through all the amazing photos from Uchiyama Aki's art exhibits on Twitter/X that started around 2017 and continued over the years. These haver photos of the displays, merchandise, signage, doujinshi, books, and drawings. I haven't really seen a share like this before so hopefully it is allowed as this is as close at it gets for most of us to being in the presence of a legend in japan.

The final pics have some artists with similar styles that shared some of his display space. That would be Kae Tanaka and Kichimushi_Atoms.
