Star Wars #62 (I think) Luke is framed for the murder of a fellow officer during a battle. So in this issue he's trying to clear his nae & it ends with Darth Vader appearing and saying "Luke, I have come for you."

As a kid I thought I'de never find the next issue. But the force was with me that day I decided to ride my bike to a convenience story I hardly ever went to. I saw the next issue, bought it (passing up Wolverine #1 by Claremont & Miller) went home and read it.

Turned out it was just a holo of Vader, but still. This was right after EMpire, & I was eager for the next Luke/Vader confrontation
