Gibson Brands, the historic maker of guitars such as the Les Paul, has accused 16 Creative, the agency behind Trump Guitars, of trademark infringement. The company issued a cease-and-desist letter, citing the unauthorized use of the Les Paul body shape.

(NEXSTAR) — Last week, President-elect Donald Trump unveiled his latest business venture: signed “Make America Great Again” guitars selling for as much as $11,500. They may not be available much longer, since Gibson has accused the guitar’s maker of ripping off their own design.
