Although the commercial publishing world has a distinction between what constitutes a "printing" as opposed to an "edition," many comix collectors regard the two terms as one.
If you have one of my old comix from the 1980s, here's how I frequently marked my comix: The first editions usually had no statement, subsequent editions generally had a circled number (edition number) followed by month/year. The example here means 3rd edition, January 1985.
I didn't do this with all my titles, but many of them from the mid to late 1980s had this type of marking.
