It's a 1 of 1 in 1:12 scale!
For those of us who were interested, a few years ago Danbury Mint was supposed to create the 1964 1/2 Ford Mustang convertible in Poppy Red with white interior. I was super excited about it as it would match my 1:1 classic that I purchased through the DuPont Registry out of Atlanta Georgia. Unfortunately, DM left the diecast market before it the Poppy Red convertible was made. They never sold them. However, a couple of years ago I acquired the prototype. Now I have it along with my Wimbledon White version. I view the DM Ford Mustangs as the best scale model of that car in any scale. It is extremely well done.
Wow! That's a keepsake. Do you still have the 1:1?
