Paul Jaray warned me that the car was featured in a recent article about "the incomplete history of Brooks Stevens motorhomes".
As it is incomplete, precisely, we don't learn much bout the particulars of this particular car, but there are very valuable details on the subject.
And four more pictures of this one, where we see the these ladies nicely chatting inside the car, on the front seat, then rejoined by a gentleman on the rear seats.
And that's all.
Here they are.
