<Tabanus> was researching a tournament held in Geneva, 1977 at the Hotel Mediterranean (l’Hôtel Méditerranée). Finding pictures of the hotel, or even its address, is proving difficult. But I did manage to find a B&W picture of the interior of a earlier 1977 game between Spassky–Portisch.
As one can see, Spassky was letting his hair get rather long, and has a look I haven’t seen in too many other pictures. The picture itself comes from the Tribune de Genève (I don’t have the exact reference at hand).
Here are the two facing each other 30 years later, from a match they held in Hévíz, Hungary.
