Tried to find my Kiki B2 earlier - found B2s for Spirited Away, Nausicaa, Mononoke, Grave of the Fireflies and Laputa, but couldn’t find Kiki! I suspect I’ve put it in a sleeve with some B1s and it’s hidden away, sorry about that. Do you need comparison photos for any of those? Or was it just Kiki that you’re worried about?
If I had to guess, I’d say all 3 in your photo are probably legit, especially if the paper stock is similar between the 3.
