I don't know much about these, but I guess Nevada Palace had a series of yellow cards with classic cars on them in 1999. Were there just 4 cars in the set? I've seen a '66 Ford Mustang, '57 Chevy Bel Aire, '56 Ford T-Bird and '61 Chevy Corvette. Were there more? If anybody has any they'd like to sell or trade please e-mail me.
