Oops, way over-due, here's the mailer. The two typefaces that I chose were Baskerville and Avenir. I chose to mostly represent them through a more abstract means, with curls for Baskerville and more geometric shapes for Avenir. I also added the birds, each made from one of the typefaces.
The inside is the portion of the mailer that shows the different typefaces listed out. This is also where I played around with the overlay, as well.
