A massive bonnet and grille...
... with a correspondingly massive boot.
Any ideas on identification?
Grille mascot is a type of prancing creature with the legend '98' below.
Rear wing details look reminiscent of Cadillac.
The mascot matches the second from left in this auction: Five American Car Mascots. It may be a false lead, as it is very similar to the GAZ Volga leaping deer. Perhaps someone was playing a joke by attaching that to a huge USian automobile.
Update: BC reckons it is an Oldsmobile 98, and TM dates it pre-1974. Good work chaps.
