Introduced in 2002, this Tyco (Mattel) twin pack contains black/red flames '60 Corvette with Blower and light green/purple flames Camaro Funny Car slot cars. These were Great Planes exclusives and were some of the very last twin packs ever produced by Mattel. Each reside on an 440-X2 chassis which are still sealed inside its packaging never removed. These have been very collectible over the years.
