Vespa 50s longtail seat

Hello, i want to buy a new seat for my vespa 50s, but the problem is i need a 2 person seat.


I ride with my girl occasionally so is important a seat that can ride with 2 persons.

i saw the beauty  longtail sport seat, it's says that can ride 2 persons. But i still can imagen 2 persons on it. Does anyone here have pics or have this seat and ride with 2 persons?
