Who do u guys think makes bingo books. Is there like. A committee? Are there village specific bingo books? I feel like there is, right? Does that mean all the villages are just constantly playing catch up with eachothers books?
Before the villages, did they still have bingo books? Who made them then? Did each clan have their own books? And different webs of allied clans would have better, bigger, more informed books because they had access to eachothers information? If there was a general "good" bingo book with the best, most reliable information, then who was compiling that? Was it a specific guy or a group? With how isolated and uncooperative so many clans were back then, if the books were maintained by individual clans, then there must have been so many types of bingo books. Or maybe there were a few specific clans who would produce them...? I can see that as a Nara thing.
Id like to believe some nin like collecting old bingo books.
From enemies, as trophies. Bought from markets or found in old abandoned shinobi bases and clan homes. Passed down from a grandfather along with stories of having faced off with the unfamiliar, powerful nin from ages past recorded inside them.... the options are limitless.
I think many nin add their own little notes to their own bingo books, opinions, doodles, theories on enemy nin, etc. So collectors will value books with notes in it, especially if the books used to belong to a famous shinobi (cool insight into their mind !!) or is really old (cool time capsule comments on shinobi from forever ago !!)
You can make some serious money on an old bingo book filled with personal notes that belonged to a famous shinobi...
Rumor has it the first Hokage's bingo book was sold off by Tsunade to cover her gambling debts. And that when the Nidaime's bingo book dissapeared into the pockets of one of his students after his death, people were straight up ready to kill to get it back— but no one knew who'd taken it (it was Danzo)
Jiriyah lost his old bingo book from the war in a bet, and was surprisingly, genuinley upset over it die to the sentimental value. It was sold for some crazy money later on, as it had personal notes and doodles from all sorts of famous shinobi inside of it
Jiriyah, Tsunade and Orochimaru all drew over eachothers photos in their section of the book, and all three left sarcastic comments in many a corners. Minato left his own comment or two, as Jiriyah asked him to sign his own page after he broke S rank, to celebrate. Then Sarutobi also left some comments here and there too, and Sakumo had actually left more than a few— signing his own page, writing a little congratulations under Minato's S rank, drawing a wolf in the corner of Orchimaru's page after Jiriyah insisted he join him in defacing it, etc.
Jiriyah's bingo book being his team's official unofficial shared bingo book... all three of the sanin tossing it around and marking off shinobi they'd fought, leaving stupid notes and doodles for the others to find later, getting other shinobi to sign it on their own pages.....
I think a lot of shinobi do similar things with "personalizing" their own books, but the sanin certainly ended up creating one of the most valuable with their own endeavors
And then in Boruto, bingo books are probable even more of a collectors item. Especially w shinobi becoming even more commercialized / sort of idol-ified
Just like how some middle aged dad's will save up their baseball card collection to one day sell, telling their children it will be their college fund one day, shinobi are doing similar things with their bingo books
(One of the most valuable editions of the bingo book was the one produced exclusively during the war with Madara, covering many, many shinobi, both dead and alive. Only so many ended up being printed, as the war ended up being shorter than expected, and while there are newer knockoffs and reprints, OG books from that period can make some crazy money.)
