So I'm looking around in one of those Collectable & Antique shops today. It was like a museum: but in the back were two piles of posters. Each has been unrolled and mounted under Saran on cardboard. Looked like someone's collection. In any case they are all in excellent shape and priced under $30 each.

The oldest Porsche poster was in German and featured an early 356; others were race specific. Several I have seen on eBay for more $$

The VW ones featured the microbus, kombi, and sedans. Never seen any of these before.

place is: a Country Collectables & Antiques Mall, 2380 A Main St, Cambria, CA 93528
It's about 12 miles south of the WCR location.

I'll shoot a couple of pics tomorrow....
