useR 2015 Conference T-shirt from Aalborg

You too can now own a conference t-shirt from the fantastic 2015 edition of useR in Aalborg. I have permission to from the designer (and main conference organiser) to print and sell these shirts.

Note - the original conference t-shirt was a mushroom grey which unfortunately is hard to match. However, the uploaded images have transparent backgrounds, so it should print well on any colour you choose. 

In the unlikely event I sell any of these shirts, (:-)) profits will go to the R Foundation.
