I managed to get my hands on an Old Petra Sloane, thanks to Boxermom who helped me track one down and went out of her way being so kind and helpful! I love love love this colour it is so neutral and beautiful. Now that I have it in my hands I can finally see the difference between Nappa and Nappa Umbria bags. The Nappa bags have a more shiny and uniform appearence whereas the NU bags are more matte in their finish and definately tonal. I've posted a close up pic of the leather so that you can see the tonal variations more clearly. I literally walked all around the house to find the perfect place to capture the true colour of his bag, because in certain lights it looks more brown I'm so excited I even went what the hell and posted some action pics (even though I hate photos of myself!!!) Enjoy!
