Acquired from the storage sale of the mangaka and software developer Yuuji Iwaki, creator of L.L. Palace and Palacesoft. This particular work is a rather saucy doujinshi by Osamu Dezaki's wife, the mangaka Rikako Kugayama, created and sold at Comiket 50 as well as being distributed via Iwaki's mail order distribution service.
Uniquely, this particular work includes an 80s manuscript by Kugayama based on Mobile Suit Gundam that she apparently never published prior. I deem these sorts of works "animator's doujinshi" as they are by animators specifically or are aligned with animators closely. Kugayama worked extensively on Manga Nippon Mukashibanashi, and while I can't confirm it directly, some sources say that she did in-between animation at Gainax on Evangelion itself.
Areas that look 'wobbly' are in fact how the manuscripts look in the actual book. I'm unsure if this is a printing issue or what. The title is based on Oniisama e... which Kugayama's husband worked on.
