That would be a really cool thing to find. If you are still in the area,(oops, just noticed you're not in the area.) check antique stores, as they sometimes buy bulk stuff from estate sales. That would usually get thrown out, but if you tell them you want some old base newspapers, they may just hang on to the next batch they find.
I have a 19" X 21 1/2" dealer poster of a 69 Impala SS convertible being driven in the desert. Looks to be gold or beige with a red interior. Got it from the dealer I worked at as they were clearing out a storage room, along with a 69 Z28 poster of the same size. Z28 is red with flat hood, black stripes, and pinstripes, and black vinyl top. Cool stuff.
