Bourget

A Parisian artist was in a restaurant when the Fourth Doctor and Romana II visited Paris in 1979, around the time Scaroth was conducting experiments with time.

The Doctor warned Romana not to move when he spotted the artist sketching her. When he told her she was being sketched, 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.

Due to the time experiments, this event happened a second time, including Romana knocking over the bottle and the artist crumpling the sketch. (TV: City of Death)

A cafe artist lived in Paris in the 1970s.

While in a cafe in 1979, he sketched Romana II, but with a cracked clock face. However, Romana moved, causing the artist to crumple up the sketch and throw it to the ground, after which he left. (TV: City of Death)
