And the rejected cover by Sal Buscema.

1985 - Sal Buscema's Secret Wars II #1

You might recall this blog entry, http://marvel1980s.blogspot.ca/2012/11/1985-cover-to-secret-wars-ii.html, spotlighting Sal Buscema's cover to Secret Wars II #1.

I came across scans of the original art for the full issue drawn by Buscema over at http://artcomicenventa.blogspot.com.es/2012/03/secret-wars-ii-1-dibujado-por-sal.html.

Enjoy!
