An apparatus and related methods includes a base attached to an upright structure (such as a street light pole), a mounting bracket that releasably engages the base while supporting a hanging banner, and an install adapter that releasably holds the mounting bracket and banner until the mounting bracket attaches to the base. A removal adapter facilitates disengaging the mounting bracket and banner from the base. The mounting bracket and install adapter (and removal adapter) are attached to a pole and engage (and disengage) remotely and without using separate fasteners, thus allowing a worker to install (or remove) banners high on the upright structure while standing on the ground. The base and mounting bracket have tapered shapes that wedgingly engage, secured by a spring-biased friction retainer. The install adapter and removal adapter have structures that facilitate remote install and removal of the mounting bracket from the base.
