Getting your own real Tardis is not really likely as there is only one Doctor and he needs the Tardis more then you do.
But the next best thing is this sticker of the Tardis as you can take it with you where ever you go.
This Doctor Who sticker is die cut and shows the Tardis from an angel so that you see two sides of it and yes one, of course, is the front. But this look gives you the feeling like it is 3D and that, of course, makes it feel that you have your own tiny Tardis.
