Question
Bill,
Hi again, it's Darric with the ac/dc Jackson Pro Series signed 1978 guitar with Bon's signature on it also.. I've just acquired an LP jacket of AC/DC's high-voltage album, but the cover isn't the usual cover. That's a reason I bought this album. It is signed by Bon Scott only and he wrote above his name (not unusual) "ROCK ON" ON THE TOP LEFT CORNER.. COULD YOU TELL ME IF THIS IS A RARE ALBUM COVER, FROM A SCALE OF 1-10, 10 BEING VERY RARE. THANKS A LOT  BILL, YOU REALLY KNOW YOUR STUFF WHEN IT COMES TO AC/DC!..

Answer
Hello there,

You also sended your question to me..
The cover you're talking about is the Original first Cover for the UK and the Italian pressing back in 1975.
The European and US version has the other cover with the lightning.

So the period for Bon signing alone can be true. Otherwise I wonder why the person didn't try to have a full signed album. At this time Bon was not so special, it was more Angus...so this is strange.
The handwriting looks like Bon's.

Greetings

Vincent
