The ornamental design for a hollowbuildingblock or the like, substantially as shown and described.
FIG. 1 is a top perspective view of the block of the new design;
FIG. 2 is a top perspective view of the block shown in FIG. 1 rotated
180° to the right;
FIG. 3 is a perspective view showing the opened block and,
FIG. 4 is the view shown in FIG. 3 except the block is only partially
opened.
The characteristic feature of my design resides in the flat ribs the edges
of which terminate near and are parallel to the edge of the block face in
combination with the recessed flat faces as shown.
