Hello!

I stumbled across this on Japan yahoo auctions, and I have been looking and comparing the signatures to ones I have found online but I would like someone who has a little more knowledge and experience as a second opinion! Thank you SO much! There are ten of them here- Deforest Kelley, Gene Roddenberry, Majel Barrett, Walter Koenig, George Takei, James Doohan, Lenoard Nimory, William Shatner, Robin Curtis and Nichelle Nicholas. The seller said that all the signatures were obtained at this particular event, and they included the flyer to further back up their story. What do you think?
