Since it's 50 years for Doctor Who, I thought I'd see if I could put together a a reasonable likeness of Doctor Who companion Sarah Jane Smith who was played by the late Elisabeth Sladen who sadly passed away in 2011.  Sarah Jane was the Doctor's companion between the Jon Pertwee & Tom Baker years of Doctor Who.  While many DW fans have different favorite compionions, think most of us agree, from the classic standpoint both Sarah Jane & actress Elisabeth Sladen were the most popular in the history of Doctor Who.
