To me, the key component to type anatomy is the spaces that exists within the letters.  The negative space that occupies the strokes of each letters and their composition seems to really contrast each typeface from each other.  The letters could be spaced further or closer together.  The stroke itself can be tighten to create a different font all together.

The size of the letters is also an importance aspect in working with typeface.  I thought it was interesting that when designers alter the sizes of each letters, they do so along the x-height axis so the word itself is aligned together.  This is one of the example I found at the MAS.

 Notice (no pun intended) the letters for the NOTICE word is all written in the same size and aligned together.  The height of each letter aligns with each other in the same axis.  Also the stroke of each line is same in length, girth, and height as well, creating a balanced look.

The letters in this poster are more transitional types, meaning it’s more abstract and less organic.  I believe it is done on purpose due to prints becoming more common.  Also the poster is serious in nature, so the more geometric the fonts are, the easier they are to read.  The letters are also perfectly proportioned and archetypal, resulting from their printed nature.  The organic structure of calligraphy was deviated away from when these designers used the more mechanized approach to the alphabet as a flexible system.
