Keep your timeline organized and neat with the Mark-It Timeline of World History from Geography Matters! This timeline is made of paper; the front has a yellowed parchment appearance with dates, while the back features marked brown lines on white without dates. Homeschoolers can use the blank side for studies before 4000 BC or to add more details than can fit on the front; because the back is not numbered, each mark can stand for 1-100 years as needed. Lines may be cut apart if a linear time line is desired. Measures 23' across the bottom and is 34' tall.
