Type 1: The first type of typography used is a slab-serif. This is identified by the slanted extra serifs at the ends of each line of each character.
Type 2: The second type is a sans-serif. This is identified by the clean cut lines and the absence of serifs at the ends of the lines of the characters.
These two typefaces are contrasting because one is much more clean cut and the other has a small decorative element. These help you to notice the differences in the words and which ones are more to the point and clear and which ones are more decorative.
These contribute to the all over design because they help the words to stand out against each other and they help the eye be guided to what is the most important thing in the quote.
