If you're gonna depict time starting with Today and moving back to the Big Bang, it's gonna be a long poster. This poster is printed on 100lb poster stock and measures in at 8" wide x 77" tall. The poster is G-rated, so it's classroom- and kid-friendly.
This is the prettier, bare-bones version of our post, made by Visual.ly. You can also find posters of our exact original post on the poster home page.
Measurements are taken of the front of the shirt. For example, a Men's Small says Chest = 18", which means it measures 18" from left to right of the front of the shirt. The full shirt circumference = 36" (front and back combined).
