authentic chanel cambon totes?

A question about a purse my friend got..Well she recently got the Chanel Cambon tote, except I'm not too sure if its authentic or not, 1.Does the authentic one have a pocket on the outside, on the side that doesnt have the CC's. 2.Is the lining on the inside supposed to be black or pink. 3.Are the CC's supposed to wrap around the corner of the bag a little. Thanks, the best answer gets 10 points.
It is the Chanel Cambon Large Tote. Its black with white CC's. It doesnt have a pocket on the front, it has one on the back.(the back is the side without the CC's)

i dont think it has a pocket if this is the bag youre talking about...

the lining is usually pink with double CC logo, and yea, the logo should wrap around a little.
