GOTG (Vol 1) #14 unpublished cover:
http://www.comicartfans.com/galleryp...?piece=1128043
Here's an unpublished version of the cover to #14. This looks as if it was intended to be published (due to Jim's various notes to the colorist, editor, and production staff in the borders- along with the "and" after his signature).
The published version is pictured in the additional images, the main differences being the taller stance of Ghost Rider and Nikki's body placed a bit lower. I do like the published version better but love the fact that I was able to secure a Guardians piece done during Jim's tenure on the series that remained in pencil form.
The cover is an homage to Uncanny X-Men #135.
