pop-up calendar so far

This is definitely my favorite project in typography so far:
The pop-up letters are the 13 most used in the English language (need to mention that somewhere in the calendar):
1.E
2.A
3.R
4.I
5.O
6.T
7.N
8.S
9.L
10.C
11.U
12.D
13.P

Each month focuses on one PMS color and one sans-serif typeface. Each typeface has a short description and a fun pop culture fact about that font. For example, the text for the title of the film The Royal Tenenbaums is set in Futura. For someone who doesn't know a lot about typography, this would be an interesting way to learn about different typefaces with references they would recognize.
