The artblog project NamelessleTTer finds itself at the intersection of image bookmarking (a la FFFFOUND!) and hidden messages that are written with the intention of being discovered (think PostSecret). The collaborative effort to leave personalized bookmarks in public reading material was created with the intention of spreading creativity and curiosity via bookshops and libraries worldwide. The main guideline for participants is to provide photo documentation of their contribution and “be as original/sensible/artistic/humoristic as possible.”  It certainly worked with a recently posted bookmark left in a copy of “The NPR Curious Listener’s Guide to World Music” (pictured above). A charming find for one lucky reader, no doubt.
