This release and its companions







Choosing one for your collection
Look at the green wing edge and the bright wheel spokes for rubbing. The busy side graphics can disguise a small chip until you inspect them closely.
If the car is loose, do not assume the livery alone proves which package it came from.
Collector questions
Can I distinguish the later two-pack car by paint alone?
The two Monster cars are very close in appearance. Original packaging is the stronger evidence for their release format.
