I have two official, imported band/guitar score books for the Blue Blood and Jealousy albums. These are thick (~250pg) score books with notes/tabs/chords for vocal, guitars, bass, drums, etc. If you want to play some X-Japan music exactly as it is, these are the official books you want. They also have various band pictures, information, etc in the back.
They are both in very good condition. They really weren't used for musical purposes, they were just collected and stored. If you are interested and want pictures let me know. Not really sure what they are worth, I would like to get at least $20 for each.
