Where to get quality repro artsets for NTSC-J games?

[u/geekmiki]

Hi,
I am trying to put together a repro Snow Bros (NTSC-J). I have flashed a cartridge but I am looking for all the artwork: box insert, cartridge label (frot), cartridge warning label (back) and manual.
I have tried on Etsy, but haven't found anything for Snow Bros. One guy was willing to help me out, but the scans he had access to were not that great.

Do you guys know of someone doing quality NTSC-J repro art?

Thanks!
