I absolutely love getting type catalogs in the mail and the most recent one from House Industries is by far my favorite. It's devoted entirely to the typeface "Eames Modern" (which I am now coveting) which was inspired by the great Ray and Charles Eames. The spreads are gorgeous. This totally made my day.
Also in my mailbox? The new RISD alumni magazine! It's been recently redesigned and restructured and I love it!
