There are several sellers on evil-bay who sell this & the others - usually in the $6-15 each range. They're basically "clippers" who get old magazines, clip the collectable ads of all types, then list them on eBay.
Just set up a search for 914 collectables or everything & anything 914, & they'll come up, then go to any seller with any ad, & then check at their "store" & other listings for what they have.
BTW - Have you ever wondered - with them both in the car holding the roof up - how the hell they get it into the trunk!!??
Really!?
A Madison Avenue "Oooops!" - even back in the day when it ran, there were comments in the press about that.
PS - One of the comments said it should read: "The Dumb Porsche" for the occupants!
GLWTB!
