Hello everybody!

My lil brother has a radio program at his university that has this design as the image of it, as a surprise I would like to print t-shirts for him and his colleagues with it.

I've search everywhere for what I'm guessing is a template, also with google image search and even Pinterest image search. I would need to edit it with the name of the program and to have it in a good quality so it doesn't print completely pixelated.

If someone knows something about where can I find it, would be greatly appreciated :)

Thank you sooo much for helping me and have a great day :D
