Know any sites with Japanese game cover art or ad scans?

[Kitsune Sniper]

I'm looking for a bunch of sites that have Japanese game cover art, or ad / handbill / flyer ads, particularly from the NES/GB/SNES era. I'm working on a new layout for my site and figured I'd add some blog header images. So far I've got three for a few of the games I've translated, but my Google searches don't turn up as much stuff as I'd like.

Does anyone know any sites where I could find these? Just... don't mention GameFAQs, most of the stuff uploaded there is very low quality.

The scans are decent enough resolution, but have watermarks. It might be good enough for your purposes, though.

I wish. sometimes you can find specific ones randomly via google images, but far as i know there is no effort to scan and share this kind of thing, sadly.

The scans there are too small. Gah.

I have found a few sites, though!

Has lots of flyers and ads from the Famicom up to the PS3!

Has cart, box, and manual cover scans for many games. (Click on the Start button to enter.) Games with a star next to their names have scans.

This place seems to have lots of scans (at low to medium resolution). I haven't dug deep into this yet but they have scans from the NES, TG16 and Genesis eras.

More handbill scans! Separated by year (top menu) or by company (right menu).
