About Eduardo de Valfierno link
By the way, Eames saw the bar's name 'cause he actually was in the bar. And I guess, he noticed this (and of course Eames knew about Eduardo de Valfierno (he was very famous forger)
I think, Arthur did it intentionally ^___^ to show him "I'm thinking about you every time"
P.S. Also “Valfierno” = “Inferno” (Inception levels look like Dante’s inferno - pic
All visual Inception stuff (the bar's design, painting and so on) was from this man - Guy Hendrix Dyas
I'm sure, he is the main Eames\Arthur shipper =))))
