These drawings were drawn between Jul and Aug of 1961. Several of the drawings have various revisions but I only have a single copy of each drawing and I assume they are the latest revisions. I hope you all enjoyed these.
If you know any details about any specific drawings and would like to add a description to any of them please submit a pull request here https://github.com/buildstarted/apollopreliminarydrawings.
I really want to give a shout out to Scott Manley. He offered some great insights into the drawings in his video about them that I was unable to get. Please follow him on Twitter or check out his videos on Youtube.
