1. A laminated roofing shingle comprising:
(a) a posterior layer having a posterior headlap portion and a posterior buttlap portion including a plurality of posterior simulated tabs extending from said posterior headlap portion, said posterior simulated tabs spaced apart by a plurality of posterior partial slots, and each of said posterior simulated tabs is connected to at least one adjacent posterior simulated tab by a connecting segment; (b) an anterior layer having an anterior headlap portion and an anterior buttlap portion including a plurality of anterior tabs extending from said anterior headlap portion, said anterior tabs spaced apart to define a plurality of anterior openings between said anterior tabs; and wherein the anterior layer is positioned on the posterior layer in a manner such that each anterior tab is positioned over a corresponding posterior simulated tab such that each of the posterior simulated tabs is at least partially covered by one of the anterior tabs; wherein the number of posterior simulated tabs is equal to the number of anterior tabs; wherein the posterior simulated tabs have a given breadth that is about equal for each posterior simulated tab; wherein at least one anterior tab has a first anterior tab breadth and at least another anterior tab has a second anterior tab breadth that differs from the first anterior tab breadth; wherein at least one anterior opening has a first anterior opening breadth that is about equal to the second anterior tab breadth; and wherein at least another anterior opening has a second anterior opening breadth that is about equal to the first anterior tab breadth.
