Please take a look at the attached photos from a buddy of mine and let us know if you agree: with the Superbird variety designation and the grade LMK if you require better pics of the reverse. Thanks!
I agree, For those new to Error collecting, this is what they are talking about. Notice the "S" on the Eagle's breast.
Not to get way off thread but a buddy of mine in high school dad was a mechanic for Richard Petty who use to race this variety, he was tragically killed in a auto accident, as a nice gesture Richard Petty gave him one of these cars was equipped with a 440- six pack and had one heck of a top end !
