Block letters:
Script:
Can anyone say, definitively, which one(s) are correct for what years?
Every '69/'70 I've ever seen had block letters, and every '72 I've ever seen had script.
But, what's correct for a '71? I've seen those go either way. Was it a mid-year change? If so, at what point in the year did they switch? Or did I just happen upon a few which had been swapped later in life?
