An advertisement mount is provided to flatly mount an image regardless of a size of the image by spreading a pair of support units outward. A pair of first rotating bodies(230) have engaging protrusions(231) on outer peripheral surfaces to freely rotate around axial pins while being coupled with a pair of support units(300) stably supported on the ground. A second rotating body(240) arbitrarily rotates around an axial pin while being engaged with the engaging protrusions of the first rotating bodies and has a holding unit(400) coupled at a lower end. A pair of third rotating bodies(250) have engaging protrusions(251) on outer peripheral surfaces to rotate around axial pins while being engaged with the engaging protrusions of the pair of first rotating bodies. Tension bars(500) are coupled with upper ends of the third rotating bodies respectively. A rotation angle control unit(260) has a stopping protrusion(263) engaged with the engaging protrusions of the third rotating bodies, a push button(261) exposed outside a body unit to be pushed by a hand, and an elastic spring(264) installed between the stopping protrusion and a rear end surface of the body unit to maintain a state in which the stopping protrusion is engaged with the engaging protrusions of the third rotating bodies by elastic force.
