The Historic NAG Jay was first created in 1966, by Neil Albert Grauer (NAG) while an undergraduate at Johns Hopkins University. Since then, the NAG Jay has been used by the university in many capacities. In 2017, a complete set of NAG Jays (one for each sport) was drawn by the hand of its original creator, creating the full athletic catalog of official NAG Jays.

The NAG Jay cannot be used as a substitute for the University Athletics logo or official sports logos. It may be used as a graphic element for informal uses, including wall art, brochures, banners, invitations, and clothing. This artwork is strictly for internal JHU Athletics use only.
