Early Famicom games question

[vnisanian2015]

Is it true that originally, Famicom games didn't have a warranty card? All complete copies of early Famicom games that I've seen on eBay (I.E. Donkey Kong, Donkey Kong, Jr., and Popeye) had the game itself, the box, and the manual. No warranty card.

Would love to know when they started including them with the games.

I have the earliest (pulse line) version of Mario Bros. and I am pretty sure the manual is the only thing it came with. I dunno when Nintendo started adding warranties.
