While non of those are the style I prefere for a wallet, the vertical model is nice. Id also be tempted to buy the billfold model in mocha for my father. He's in need of a new one and that looks perfect.
It's a shame there are not more color options. I feel like smaller leather goods like a wallet is a great opportunity to expand your leather colors. Maybe a green similar to the shade that someone requested in this threads before for example.
