Complete Marvel Chronology - 1973 (missing from 1970s pack)

The Complete Marvel Chronology is a project started long ago and refreshed in 2014 and later to release all Marvel comics from the beginning to present. Some books are only available as low-quality scans, but this is as complete as possible. This is by no means an all high-quality digital collection, but the closer we get to the mid-2010s the higher the quality gets.
This is the 1973 year that was missing from the 1970s pack.
