This may be proof that the each member of NAOTMAA took the photo of another member at the same photo session, which could mean that each one of the IF member had at least one photo of another one in his/her album:
What I wanted to say -- these two photos were taken by
at least two persons at the same time! ;-) And could be found in OTMA's and AF's private album, for example.
Photo credit goes to L.Mabee's site FrozenTears. (The first one).
