    University of Cincinnati: Neil Armstrong's Handwritten Lecture Notes (Eight Pages) and Hand-drawn Diagrams (Nine Pages) on the Portable Life Support System (PLSS) Directly From The Armstrong Family Collection™, Certified and Encapsulated by Collectibles Authentication Guaranty with a Photo Certificate. Four lined 8.5" x 11" leaves, written front and back, removed from a spiral-bound notebook beginning with: "Today we'll talk about an example of System Design...". This is a fascinating exposition of the development of the spacesuit and PLSS based on the Gemini EVAs and on through the Apollo program. The slides offered here are referred to in these lecture notes. Also included is a 4" x 6" sheet with handwritten notes as found with this material. An absolutely incredible offering- seventeen pages in total regarding a subject on which he had quite a bit of firsthand knowledge. How exciting it must have been to hear him lecture on this subject! Very fine. The lecture notes are sealed in numbered archival sleeves; the diagrams are in individual sheet protectors. This lot will include encapsulated CAG Photo Certificates with Statements of Provenance signed by Neil Armstrong's sons, Rick and Mark.

    This was my first time dealing with an auction house, and I am 100% completely impressed with Heritage. There is not an aspect of this process that I have a critique for.
