"Visual Brightness and Form of the Magellanic Clouds" (1958) and "The Visual Milky Way" (1960) by Sergei Gaposchkin
Here are a couple of reprints of papers by Sergei Gaposchkin that were published in "The Irish Astronomical Journal" (1958) and "Vistas in Astronomy" (1960). The papers are titled "Visual Brightness and Form of the Magellanic Clouds" and "The Visual Milky Way". Both papers feature sketches made by Sergei Gaposchkin. Of particular interest is the Milky Way sketch that Sergei falsely boasted to be the first full visual representation of the Milky Way ever created. Sergei Gaposchkin was a Russian astronomer that immigrated to the United States in the 1930s and was the husband of the astronomer Cecilia Payne-Gaposchkin.
