Being you made these for someone you are probably OK but I suggest be careful if you do try to sell blanks with logos like this. Unless you pay for the rights to use them they will come after you. Especially team sports. They want their money. Seen it first hand with scrollsawn items.
How bout that Kody Walker? Heck of a player but needs to learn how to spell his name properly! I almost fell out of my Lazy Boy when channel surfing and hearing that I had just scored a touchdown.
