That's what mine says too, go mango.
Here are a couple pictures of my promo set, the one picture is a few years old. I had the red '73 with no box, but later sold it after I bought a yellow '73 with box and decals.
I wish I had a red '70, as my Challenger TA is FE5.
I keep my promos in bags in my display cabinet to keep them from getting dusty.
I always wonder why they never made a '74 promo, MPC had a '74 annual model Challenger?
