This batch includes the April through September 1943 issues. The April 1943 issue is the last of the “bedsheet” issues. Astounding went back to its earlier format after the April issue, and even that would not last for long. Soon the premium on paper during the war would push the magazine down to digest size.

The September 1943 issue takes me to Episode 50 of my Vacation in the Golden Age and means that I have a complete set of the first 50 issues of Golden Age-era Astounding. I skimmed the contents of these issues and they are going to be fun.
