About T-Shirt Design
One look at Best Grandpa by Par Funny T Shirt and you pretty much know what kind of sense of humor it has. Fans of grandpa humor will probably get the joke first, but it is simple enough for almost anyone to understand.
You could wear it for birthday, bring it out for Christmas, or just keep it in the normal shirt rotation. It works well as a novelty t shirt because the joke is clear and the design has plenty of personality. It also fits in with funny t shirts for men that are more about a quick joke than a huge graphic. It feels casual enough for normal days but still has enough personality to get noticed.
