West Coast Avengers #42 Marvel 1989 - "Visionquest" starts - WandaVision TV

It started here - Visionquest - the search for the Vision, the intro of the White Vision and the basis more or less for the WandaVision series

And John Byrne started as writer / penciller with this issue

Book is at least very good or better - some slight wear and the back cover seems a little yellowish on the spine - not sure if it was printed that way or not

and a little mark on the back covet, top left
