I can remember about 20 years ago when a guy I knew was telling me what a great discovery he made when he noticed that regular calendered vinyl was translucent, how much he was making using it and charging for cast! I did end up trying it, we had a customer who did temporary electric faces for promotions and the stuff actually looked pretty good, but it was only up for 6 months at a time. The place changed owners and the new guy didn't use us and left the last special face up for years, looked like this after a while.
