I'm thinking you can do something with this shirt since every one seems to love it. I assume you are going to Lisbon, but even if not - this shirt would sell through the steemit marketplace or whatever it may be called.

It's a hit right off the bat and someone like @stephenkendal could help you get going. Maybe you could get this done locally and help the local economy like I know you were wanting to do.

None of us will look at good as you but we can all dream!
