Dream Fossil is a collection of various short stories written by the late Satoshi Kon and whether you will enjoy this manga will largely come down to one question: Are you a fan of Kons other works? If your answer is yes, then pick this up right away. Dream Fossil offers an unique look into the career of one of the greatest directors anime has seen to this day, and although not all stories are equally fascinating most are very entertaining. If you pay close attention you will notice that some stories are very similar to some of Kons movies - Beyond the sun feels alot like the later half of Roujin Z and Joyful Bell shares similarities with Tokyo Godfathers, among others.
The stories that stood out the most were Beyond the sun, a hilarious yet thoughtful story about an old lady’s trip to the sea, Baseball Brats, a simple story about an encounter between to young Boys and Joyful Bell. The latter is a heart warming tale of a young man trying to find the mother of a runaway girl on Christmas Eve.
It is very noticeable that this manga was made shortly after Kons entrance in the manga industry and thus sometimes lacks a certain touch but the detailed artwork and surprising twists make more than up for this.

There is an interesting interview with the musician Susumu Hirasawa, photos of some items Kon was fond of and a very touching poem by Kons editorial department in the back that I found very insightful.
If you are searching for something to read until the still uncertain release of Kons final movie, The Dreaming Machine, you should check out Dream Fossil.
