U.N.I.T. Artefact #25561-A

Hidden away in the Black Archive is an unusual portrait dated back to August 1787 (Osgood is trying to find out who the painter is). Titled "Hello Sweetie", it shows River Song, a known compatriot of the Doctor (rumoured to be his wife), and also a fellow time traveller. She is also the daughter of Amy Pomd and Rory Williams.

Examinations of the painting have detected a low level pyschic field emanating from from it. It is similar to the one emmited by the Tardis, which explains why it hasn't attracted public attention over the years.

Further analysis has uncovered a hdden signal, possibly a message, but our experts can't decipher it. Under the instructions of Kate Lethbridge-Stewart, the Doctor has been contacted, and we now await his arrival.
