Note: According to FantLab title 48329 and http://archivsf.narod.ru/1927/sergey_drugal/index.htm, this story was first published in 1984. However, the first appearance of the Hungarian translation was in 1980. The Hungarian text is available at http://www.scribd.com/doc/147143228/galaktika-1980-039 and the Russian text at http://books.rusf.ru/unzip/add-on/xussr_gk/drugas21.htm?1/2 . It would appear that the Russian text may have originally appeared prior to 1980, but the details are not known.
