Thanks to Terry Hoknes at Hoknes Comics for the info and write up.
Due to a change in policy at Image, they started to over print comics to prevent the books from selling out and going back for reprints. They did this to allow more readers to get copies, and save on having to go back to the printers. Due to this, Image Comics now vastly overprints all new books, especially new #1’s. So now, if a book sells out its really a surprise and might be the only future big money books.
