I’m not sure exactly what’s going on in this illustration, but the young comrade seems to be having a good time, even though both the tree and the bird are rather distressed.

At the top, it seems to read that the diode tube, plus “plasma”, plus “reactor” equals whatever is in the bucket that is powering the tool. So very possibly, this young man went on to a career in science, such as designing the Chernobyl nuclear plant.

Whatever it is, it appeared in the October 1961 issue of Юный техник (Young Technician).
