"Unusual Tales", a series presenting Steve Ditko's comics from 1957 to 1959 that are in the public domain.
But before the story, some links:
160 page book of classic 1970s Charlton available
Published bi-monthly, back issues available
Two Ditko Omnibus volumes from DC coming out this year
Scans in this series generally adapted to my personal tastes from those copies
