Tapestry
From Tardis Wiki, the free Doctor Who reference
A tapestry depicting the red lady was part of Dr Francis McCallum's collection. Professor Walter Pritchett was the first to look at it, causing him to be killed by the red lady. (AUDIO: The Red Lady)
Robert Dudley noticed a tapestry in Elizabeth I's court change in front of his very eyes as a blue box suddenly appeared. As he was stuck in this time period for five years as a result of the Time Fracture crisis, he believed it meant the Doctor was going to do something about it and rescue him. (WC: Is anyone receiving these transmissions?)
