A decorative object assembly for attachment to a vertical surface includes a substantially planar decorative block defining an upper edge and a lower edge. A flexible planar strip is made of a thermoplastic polymer, and defines an upper edge parallel to the upper edge of the block, a lower edge parallel to the lower edge of the block, and a vertical direction between the upper and lower edges. A first layer of adhesive extends vertically downward from the upper edge of the strip, for releasable attachment to the vertical surface. An attachment mechanism for attachment to the decorative block is configured on a lower vertical section of the planar strip. A gap section of the strip is vertically located between the first layer of adhesive and the lower vertical section, on which no adhesive is adhered.

A mounting system for releasably securing an object to a walled surface is described. The system comprises at least one magnetic element; a magnetic counterpart coupled to the object and configured to magnetically engage with the at least one magnetic element; and a mounting plate having attachment means for securing the plate to the walled surface. The mounting plate comprises an exterior surface for releasably securing the object thereto; an interior surface for securing to the walled surface; an indentation in the exterior surface for receiving the counterpart; and one or more recesses in the interior surface, said recesses contained at least partially within the boundary of the indentation on the exterior surface. The at least one magnetic elements are located within the recesses and the counterpart is coupled to the object to magnetically attach the object flush to the mounting plate when the counterpart is received in the indentation.
