Three men with radio equipment in a room

Photograph of an event. Three men are in the room. Two are sitting at a table with radio receiving equipment, both wearing headphones, one in a light shirt, the other in a dark sweater. The third stands on the right, reading a magazine. Paintings and posters with the inscriptions "After reception, ground the antenna!" and "Labor laws" hang on the walls. Books and a statuette are on the table.
