This is the perfect all-in-one Typography Reference sheet for graphic arts and graphic design classes. It explains em/en dashes, the categories of typography, point sizes, drop caps and much more. The pdf is 11x17, but it can be printed on letter size paper, as well. There are a total of 4 letter size sheets or 2 11x17 sheets.
I used this as a informational handout and reference sheet for tests.
