A mount for mounting a sign to the post of an associated structure includes a base element fixedly mounted to the post that defines a hinge region and a base plane, and a support arm having a shoulder mounted at the shoulder to the base element. The support arm is pivotable about the base element between a first position parallel to the base plane and a second position transverse to the base plane. A pair of springs extend between and connect the base element and the support arm. The base element and the support arm are engaged with one another, and are maintained engaged with one another, only by the tension of the springs.
