This minimalist yet retro-looking letterhead would work for a diner. The red, white and blue color palette gives the letterhead a very classic feel, which is appropriate for a diner or burger joint.
Of course! This graphic design template may have been inspired by a particular industry but if you like the way it looks you can change the wording and elements to suite your own need! Once you buy the file just open it open and change it however you like!
