He's been around since 1963 (and the Timelord himself is over 2000 years old!) So by rights, The Doctor deserves a Coat of Arms! Referencing the props which each doctor carried and used enabled me to represent each of the 12 incarnations of The Doctor.  Stick in a Tardis, a couple of Sonics, and a VERY long scarf and the result is a timey-wimey Crest The Doctor would be proud of! Allons Y!
