Best glue for Rollie skin

[Shaps]

I just looked at my nearly new Rollieflex T for the first time in a while and see the covering material (leather?) on the back corner is starting to peel off.
what is the best glue to put it back?

Probably Pliobond; it's generally available (Ace Hardware) and it sticks well to both leather and metal. Also comes away cleanly if you ever want to replace the leather.
