Hello, I'm new here. I was hoping that someone who collects older Archie titles might be able to help me. I recently bought a small lot of titles from the early 70's, and some of them had a circle logo, rather than the typical rectangle in the corner. I looked on the first page, but there isn't anything that seems to indicate that it's an international edition and all of the advertisements have U.S. addresses on them. Can anyone tell me where these are from? Thanks.
