Kyushu University have made two ehaisho 絵俳書 “illustrated haiku books” from the 1760s available online: Umi no sachi 海の幸 (“Bounty of the mountains”) and its sequel Yama no sachi 山の幸 (“Bounty of the sea”), edited by Sekijukan Shūkoku 石寿観秀国, illustrated by Katsuma Ryūsui 勝間竜水. Pictures of marine and montane (respectively) flora and fauna, plus haiku to go with.
These two books join the rest of KU’s Rare Books Collection (check the “With fulltext” option to limit your search to items that you can view online). They’re also at Waseda University’s Japanese and Chinese Classics, but the versions there appear to be different and KU’s scans are much crisper.

Here’s an interesting book I found in Waseda’s Database of Japanese and Chinese Classics: A Thousand Characters and One Hundred Forms of Seal Script Calligraphy by Sages from Successive Dynasties 歴朝聖賢篆書百体千文, apparently by Sun Zhixiu 孫枝秀 and Zhou Hong 周霟. (English translation of title courtesy of Rebekah Clements’ A Cultural History of Translation in Early Modern Japan.)
I’m skeptical that any sage found much use for “crane script” 寉書 (p 39, far left) or “turtle script” 亀書 (p 23, second from left), let alone “great pole seal script” 太極篆 (p 40, second from left), but I’m pretty sure I independently invented “wooden tablet writing” 木簡文 (p 49, far right) on my binder in middle school.
