I have all three of Informantors under Bobby's picture (is he drinking wine?!, I suppose he invited a girlfriend on chess) numbers 19, 20 and 21.
(At the time I was junior player, and my present day OTB repertoire is still hanging with those days {Velimirović, Adorjan, Zonal tournament in Vilnus etc; I have notebook in which I noted openings with graffiti pencil from that period}, and I have bronze Infomator from1970 and that pidgeon-blue from 1968 with Fischer's games from tournament in Vinkovci.
First annotations were short, almost non-existing compared with Adorjan's and Huebner's glosses from seventies.
