Quoted from ElectricCircuit:Just found a set in my shop from a while back. Believe they are NOS. Is there a way to tell if they are NOS? Like on the backing or something? Also what are they worth? Might as well put them up for sale.
South Park art was screened to the cabinet - there never were decals for Stern games until Transformers. So - these are aftermarket, not something from the factory.
