The Chronicle Books Blog is featuring some of the artsy-craftsy mailings they've received over the last year--the publisher of singular books highlighted some singular book promotional tools.

Above is a "pribery" kit created by illustrator Michael Slack to show off the different styles and formats of his work to the publisher. Other beautiful mailings included a charming origami packet and monochrome embossed envelopes from unconventional PR firms.

Here's more from the post: "We also get a lot of promotional material that's as diverse as the books we publish. For example, below (from left to right): letterpress "matchsticks" from Swink, a wooden postcard from Deep Craft, a multimedia card from Laura Tarrish, and a tiny letter from Sally Faulkner."
