A pendant I designed around the opening credits for the 2011 & 2012 Dr Who TV show, where the DW letters revolve to show the TARDIS on the reverse. Here I have created a stylized TARDIS.
Now at 8.5cm in height you can hang it around your neck or from your car rear-view mirror! Of course I recommend getting it printed in Royal Blue!
