In case you did not know, Regan Smith Clarke has released a new line. There are t-shirts and longsleeves, which focus heavily on clean and simple graphics. I do not mean simple as in crappy designs, but the simplicity gives the design a certain elegance that only leads to positive feedback. Take a look and maybe there will be something you would like to purchase.
My personal favorite, The Highest Quality Seal
On a side note, I've noticed other companies using a seal as well. Maybe this type of design is very effective for business.
Old Inventions Longsleeve It is a unisex shirt.
