The T-shirts are made in tremendous quantities by the likes of Hanes or Gildan with a tag in the collar that shows the company name/logo and country of origin. Quite often the artist or IP owner of the printed art will include a trademark or copyright symbol as appropriate into the artwork. The printing company often goes uncredited.
