One of the new-fangled GMA tournaments, held in Bilbao, Spain in 1987. Twinlark asked about it, and I found this interesting picture of some very well-known, but then young, players.
A group photograph of the participatants:
Can people help identify these players? I think I recognize Andersson, Polgar, and Karpov (all standing, left to right).
