Here is the second installment in my complete representation of the General Electric information series, Inside the Atom from 1948. Since the previous one was from 1946, there may have been one in between I have never seen.
For some of the later books, George Roussos used the pencils of some of his collegues (including Mort Meskin). There is nothing to suggest he did not do it all himself here, especially in the figures and faces.
