The story, entitled Inertia, was the first appearance of the Crow (Eric Draven):
The Crow also appeared as a pin-up on the back cover of the comic below:
Near the start of July 2018, the CGC registry contained 467 recorded gradings of Caliber Presents #1 with 58 at the top grade of 9.8 Near Mint / Mint (ten of those on Signature Series labels).
These comics are not too difficult to get hold of on comic shop websites and auction sites with a number usually available at reasonable prices but top graded CGC copies do go for a premium (expect to
pay around $1,000 for a CGC 9.8 copy).
