DC Comics and Thundercats artist Dan Norton pitched a Doctor Who Cartoon to the BBC that was unfortunately rejected - but now the artist has lifted the lid on a few pieces of concept art for his cartoony take on the Time Lord.

According to blurbs Norton posted with the art, he came close to having the pitch accepted, but ultimately the BBC didn't want potential resources to be drawn from the production of the TV show:

Yeah man, we were so close… Had a few revisions creatively that were requested and so we retooled. It was going to be epic man. End of the day, BBC didn’t want anything to distract from production of the tv show.

Well, what was close to happening didn’t. Since the BBC eventually passed on, you will be rewarded with! This is the pitch poster I had only 7 hours to do. Starting to with first Doctor, the series would have touched on all the versions and filled in some gaps.

Check out the full pitch poster below, as well as some of Dan's concepts for the various incarnations of the Doctor:
