Abstract: A letter and the like having a self-adjusting orbital pin-mount for installing the letter and the like on walls and other surfaces, comprises a first member secured to a letter and extending rearwardly therefrom, an angularly and laterally yieldable spring member engaged at one end thereof on the first member, and a second member engaged at the other end of the spring member, whereby the second member thus automatically aligns itself to both angularly and laterally misaligned holes in walls or other surfaces to which the letter and the like is to be mounted, preventing stress and damage to the letter or pin-mount in the event of misaligned mounting holes.
