We already know that Peter Capaldi was a major Doctor Who fan as a child. He even petitioned to run the official Doctor Who fan club in 1972.
This beautiful sketch of the TARDIS comes is yet another bit of fan art by a young Capaldi who submitted the illustration along with the short piece on the show’s opening titles featured in the link above. They appeared in the May issue of the Doctor Who International Fan Club Magazine long before Capaldi was in line to play The Doctor. Sort of feels like things have come full circle.
