This doesn't seem to be widely known; perhaps it is and no one besides me cares.
The cover of Orson Scott Card's Ender's Game (Tor Books, 1985) is recycled from a 1983 issue of White Dwarf.
Ender's Game:
White Dwarf #41, May, 1983:

The only reason I care is that I've always thought the art was a pretty poor fit to the contents of the novel, but it doesn't seem to have hurt the book none. Given how poor a fit the art for Speaker for the Dead is to the contents of that book, I've always assumed it was also reused art. (It's in the same style as the earlier cover, but is not also a White Dwarf cover.)
