Freegun

 These are what I believe to be a French brand.

I bought these a few years ago while in France and at the time really liked the look of modern art printed on underwear I say modern art  it could also resemble graffiti..yeah thats it its graffiti.
There are hundreds of designs which are still being available to buy.
Definitely a brand to make a statement when wearing and the fabric is great against the skin.
