Here are 3 new designs out of the UK.
Notice the shaped Sonic tag on each one. Interestingly, there are 2 Amys, one pink, the other blue, with their own pattern of stripes. The Sonic is a normal X stock art, in an 'x' shaped background with an abstracted name on the edge, and logos on the sleeves. All the shirts are highly decorated and nice. But where are they available? Are there better photos? Photos used without permission here...so they are small and marked.
