If you don't mind me making a suggestion... here is a link to a shirt that we used for our oilfield business to make T-Shirts with our logo on it. It's the finest T-shirt I've ever owned. They're light, strong and extremely comfortable. Cotton/polyester. I've got a few that I swap out so ime wearing one almost everyday. That Smokey Branch camo is by far my favorite pattern.

I'd like to have a shirt with a scene of a hog with a couple dogs on each side of it. Don't go into much detail, just the outline of the hog and dogs in white. Nothing that can really even identify what kind of dog it is but mostly resembling a cur or hound. I would be all over something like that.
