To celebrate its 40th anniversary, Pensions & Investments magazine did a special issue that featured this huge timeline that streteched across the bottom of 16 pages. It was extra challenging because the amount of text and photos in each year varied greatly plus--due to ad placements--the number of columns available on each page was different. I designed it as one huge file in Adobe Illustrator using 16 artboards of different widths. It took a lot of planning.
