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.
