Abstract: A fastening device is provided for hanging a picture or other wall object on a wall. The fastening device includes a clear, flexible, non-resilient carrier having at least two mounting hooks in parallel alignment which are secured to the carrier for engaging wire mounting means on the back of the picture or wall object. This permits the device to be used on irregularly shaped or curved walls or walls with imperfections. Alignment grooves may be provided at opposite ends of the carrier to facilitate proper alignment of the carrier on the wall. Affixation means in the form of either a nail or adhesive mounts are provided for affixing the carrier to the wall. A leveling device, preferably a bubble level, may be included in the carrier. A companion method for hanging the picture or other wall object on a wall using the subject fastening device is further provided.
