--Edit--
I've managed to track down both the Arc the Lad poster and Lunar: Eternal Blue poster. Thank you very much to everyone who responded!
I would like to shift my focus now to the following posters. If you have any of the unconfirmed posters, please let me know, even if you're not willing to sell. If you have any of the confirmed posters you'd be willing to part with, please let me know as well!
The posters:
Shining Wisdom
Albert Odyssey
Raystorm
Vay
Popful Mail (do not know if this even exists)
Elemental Gearbolt (do not know if this even exists)

I need to waste my money.
Working Designs offered free posters for both Lunar: Eternal Blue and Arc the Lad when you bought the strategy guide. I never sent in for them. I don't know why. I sent in for the others...
Please sell them to me. I'll pay top price for them if they're still in good enough condition to be framed.
Would also buy posters for Vay, Shining Wisdom, Albert Odyssey, Raystorm, or Elemental Gearbolt (if it exists).
