this bakemonogatari manga end card of hanekawa tsubasa illustrated by yo asami, the illustrator of the okitegami kyouko manga, forever lives in my mind
good lore that has come from official monogatari art that's not the anime or the novels:
shinobu makes her own donuts (puc puc)
hanekawa makes her own clothes (misc/anniversary stuff)
oshino looks sexy in a suit (manga)
karen & kanbaru go on an amusement park date (puc puc)
