It’s that the label inside the body was changed to a red label in April, 1968.
A carved seal of a side board inside the body can check the making time present.
But the difference by which a sale date is slightly seems something to have that.
I’ll inspect at the reach I know.
This label is a red label of the immediate early stuck on an individual like a specification in a light green label period.
The logo of “YAMAHA GUITAR” recorded on a label is square font.
It’s pink whether the label is the purpose it doesn’t take for painting to the top.
