I absolutely love Etsy. It seems to have an almost never ending supply of great letterpress prints. My newest favorite of the bunch are these from ModernPOP. They have a great selection with everything from calendars and cards to prints to hang on your walls. The style of the whole collection is as the name would imply a combination of modern and pop art. All the illustrations are printed on 140 lb weight cold pressed watercolor paper and printed with archival pigment ink.
