Can a Final Fantasy fan identify these signatures?

[Ayatane]

Hello everyone!

I was looking at stuff on Ebay and came across this item:

http://m.ebay.ca/itm/Final-Fantasy-V...770?nav=SEARCH

The seller doesn't know who signed then and I don't recognize them either. They don't look like any big names of the game production.

The link with the original owner has been lost so he doesn't know from which event it comes also.

Any clues?
Thanks alot!
