Release of Heroic Tales: The Bill Everett Archives Vol. 2 has been delayed because editor Blake Bell is still searching for two stories to complete the book:
Silver Streak Comics #1 (Dec '39) – text story with two illustrations by Everett
Target Comics v1 #8 (Sep '40) – Chameleon 6-page story
Blake (and us) are offering a free copy of the book and credit in the acknowledgments to anyone who can direct us to someone who has an unslabbed copy of either of these comics. (The owners of the comics will also get comp copies and acknowledgement.) See Blake's blog for more info.
