Well, it took me all day, but I finally finished going through every one of the Sunday sections in my collection. All together, I have 518 sections, from 58 different newspapers, spreading throughout the country. I have 138 editions of the Stars & Stripes comics, spreading from 2002 to early 2008.
And this will grow every week, when I get the Sunday paper. Oh well. At least I finally have the spreadsheet made.
