My mom had a nice little notebook for passwords. But when she passed, we couldn't find it anywhere... We went through the whole apartment, everything.

Not having her passwords made a lot of things harder, closing her accounts, accessing her laptop, phone, etc. So while you shouldn't advertise it, do tell a few people where to find it if they need to.

INTERNET PASSWORD LOGBOOK is probably a paper slip that you can remove, and then it'll just be a blank leather journal.

Now a REALLY secure physical logbook would just have the cover of a boring, unremarkable-looking book on the outside.
