This is an original, not-for-sale board with a handwritten signature by Kenichi Muraeda, the author of "Shin Kamen Rider SPIRITS." It's about as thick as thick cardstock and is approximately B4 size. At the now-defunct Nakano Sunplaza, they used to hold talk and signing events about once a month, inviting actors and people involved in special effects works. On one occasion, Mr. Muraeda unexpectedly visited, and a signing session was suddenly held. I received this original board at the venue and had him sign it. The two black lines in the upper right of the signature are from the tip of a pen on the table accidentally touching the board after the signature was written. Mr. Muraeda tried to erase them on the spot, but they wouldn't come off. I considered using correction fluid, but I thought it might make it worse, so I left it as is. I got this signature on a whim at the time, but the truth is, I've never read "Kamen Rider SPIRITS" to this day, and I didn't have any particular attachment to it, so this board has been sleeping in my closet... I feel bad keeping it in this condition, so I've decided to let it go this time. If you will cherish it, please consider purchasing it.
