One of the types of Famicom ephemera which I enjoy collecting the most are chirashi (mini posters/ flyers) that were handed out back in the day to advertise upcoming game releases.
I like them mainly because they look cool and are the sort of thing that look good when framed and hanging on your wall. Like my Gyrodine and Sky Destroyer ones, which have awesome artwork on them:
I picked up a small lot of them off of Yahoo Auctions the other day that just arrived in the mail. I`m pretty happy with them. Most of them were actually Famicom Disk System games, like Metroid here which is probably my favorite of the lot:
And Super Mario Bros 2:
Zelda no Densetsu:
The only thing that I dislike about collecting Famicom chirashi is the price - they are pretty hard to find so the prices likewise tend to be on the high side and bargains are few and far between. Still though its kind of worth it for the cool artwork. They also have cool stuff on the back, like this one which explains how you can re-write games on disks:
Collecting chirashi is actually one of my main non-Famicom collecting pursuits too. In addition to advertising video games they are also used for a lot of other things, including movies. Japanese movie chirashi are actually in some ways even cooler than the Famicom chirashi. Japanese movies almost always have unique paintings commissioned for them which are reproduced on the chirashi. The artwork, which often combines familiar scenes with bold looking kanji, make them look pretty awesome. Like this poster from You Only Live Twice, with the 007 in big type, with the title in kanji below. Totally epic:
Same with this old school Battle Star Galactica from the 70s:
