I know a guy in Maine, who is selling his collection of Porsch ads that he has framed. There are 911's, 968's 944's {no turbos though} there are 924's, at least 1 Sebring edition red in colour and at least 1 Carrera 4 with a caption "Pray for bad weather" There are a lot of them, I will get a list of all the Porsche models he has.

An example of the '79 Sebring ad:

It has the car on top with "Porsche 924" in big letters at the bottom. With this as text:

THE LIMITED EDITION Sebring 79. ONLY1292AVAILABLE.

I'm buying a few {at least}
And this guy won't stiff you either. I have known him for a while and he has sold and bought many parts online, so he's good to deal with.
I can't find his email as I'm late for work. PM me or post here. I'll get a few pics of the ads to show you guys.
I can't wait to get mine!

 

These were taken with a camera phone. I think he's unpacking the digi cam now.
