Patent ID: 6893192

Claim:
A wall having a front surface and a rear surface, the wall comprising: at least a first lower course and a second upper course, each course comprising a plurality of first, second, and third blocks; each block having an upper surface spaced apart from a lower surface, thereby defining a block thickness; each block having opposed and substantially parallel first and second faces, thereby defining a block length, the area of the first face being greater than the area of the second face; each block having opposed and non-parallel side surfaces, thereby defining a block width, the first and second faces being orthogonal to one of the side surfaces, the width of the first, second, and third blocks being different; and the blocks being positioned in the courses such that the front surface of the wall is comprised of the first faces of a plurality of the first blocks, the second faces of a plurality of the second blocks and the second faces of a plurality of the third blocks to thereby provide a front wall surface having the irregular block pattern.
