I’m a sucker for any movie that has cowboys, dinosaurs and Freda Jackson warning “Gwangi! Gwangi!” So imagine my surprise to discover what an EBay vendor says is Willis O’Brien’s large preproduction model for an unproduced film from 1941 – later made by Ray Harryhausen as “The Valley of Gwangi.”  Bidding starts at $16,499, or Buy It Now for $19,499.

As with anything on EBay, an item and vendor should be evaluated thoroughly before submitting a bid.
