Original handpainted painting of Sputnik III. From a private collection. Beautiful done. It is painted with ink and probably water paint to fill the colours in. It is painted on a smooth glossy paper where the edges are reinforced with a strip of paper. It is stuck at the corners in a sort of folder to protect them.
Sputnik 3 was a Soviet satellite launched in 1958. The scientific satellite carried a large array of instruments for geophysical research of the upper atmosphere and near space.
