The T.A.R.D.I.S. as a tshirt!
Your very own Time And Relative Dimension(s) In Space shirt
(I was trying to come up with a witty “bigger than it looks on the outside” quip, but nothing I came up with didn’t sound dirty)
Again, feel free to pick your colour, but do you REALLY want it any other colour than blue?
Updated colour that works better on the Dark Blue Shirt
