Hey Gerry,
I do enjoy seeing this type of prelim as it lets you get a glimpse of the artist's creative thoughts. Love the Paul Smith thumbnails and concept pieces - great stuff!
I've attached a few prelims including -
Adam Hughes She-Hulk Prelims
Adam Hughes Wolverine & Nexus Prelims
Mark Schultz Xenozoic Tales Collection Cover Prelim
Best,
Royd
