Bourget (PROSE: City of Death) was an artist from Paris.
While in a cafe in Paris in 1979, he sketched Romana II, but with a cracked clock face. The Fourth Doctor warned Romana not to move when he spotted the artist sketching her. When he told her why she quickly looked and knocked over a bottle. The artist, frustrated, stood up and threw down his pencil. He tore and crumpled the sketch, then threw it on the floor and left.
Then, due to Scaroth's time experiments, this event happened a second time, including Romana knocking over the bottle and Bourget crumpling the sketch. (TV: City of Death)
