Images from 'All My Friends Are Dead,' a morbid "children's book for adults" by Jory John and Avery Monsen, has just become one of the most reblogged things of all time (of all time!) on Tumblr. The book depicts people and things whose friends are all dead, like dinosaurs, dodos, expiring milk and old people (*sniffle*).

While the book is kind of sad, the art is really cute, and the first 10 pages have been made into an easy-to-reblog animated gif. That helps explain how it got to 18,000 Tumblr notes and counting. (There was also a little help from our friends at The Daily What.) The whole book isn't online, but it's available on just about every bookseller website around.
