The ornamental design for the building block toy, as shown and described.
FIG. 1 is a top plan view of the building block toy showing my new design;
FIG. 2 is an exploded perspective view for clarity of illustration only;
FIG. 3 is a perspective view of FIG. 1 taken from generally the same
vantage point as FIG. 2; and,
FIG. 4 is a bottom perspective view taken from a vantage point generally
directly below the FIG. 3 vantage point.
The building block toy comprises a plurality of building blocks arrangeable
in various configurations. The individual blocks have spaced top and
bottom walls and side walls extending between the top and bottom walls,
which side walls, including the side walls or side-wall portions that do
not appear in the drawing figures, have unornamented surfaces. The drawing
figures are lined for color.
