I started a @wikipedia page about Mamman Sani in 2022 but it never made it past draft status and ended up getting auto deleted by the deletion bots. Looking in my history today, I had some unread notifications that the page was deleted for lack of edits. The good news is that in the mean time wikipedian https://en.wikipedia.org/wiki/User:Hold_your_horses started a new article that was properly sourced and now this great artist will get more of the recognition they deserve...
