Reply to "Williams passenger silhouettes in color?"

I have this set in Lackawanna.  They only did the color silhouettes for a few years at most in both the small cars and also in the 20" scale cars.  Compared to the standard black and white ones, I find these quite attractive.  I suspect copies would be the best way to replicate these as they are not common.  I wouldn't go as far to say rare, but still something interesting and different.
