Mrs Lizzy - I once saw a humourous travel book called "When You Start to Look like your Passport Photo, It's Time to Go Home"! I can SOOOOO relate to that. My current photo makes me look like a ghost, and unfortunately unless I "lose" it, and pay a fine for doing so

I'm stuck with it till 2013. Oh well!
Anyway, back to the ladies....yes, I think you're right about the eyebrows. Also, having had a better look, their chins and earlobes look slightly different, and the hairstyles (but of course they can change from day to day). Definitely different blouses.
The remainder of their faces are very much alike though. They have to be sisters, I think.
