Publication number: 20100028603Abstract: A camouflage pattern characterized by a textured background simulating the bark of a tree and a random pattern of tree limbs, branches, twigs and leaves superimposed upon the textured bark-like background. The limbs, branches and twigs are of dissimilar size or caliber, and extend in all different directions. The leaf elements are of differing size and color and have differing orientations. The overall look or visual impression conveyed by the unique camouflage pattern of the present invention has been found to simulate the natural look of a forest, or more particularly, the look of tree branches, limbs, twigs and leaves that have fallen onto a forest floor. The camouflage pattern of the present invention may be used on a wide variety of articles including clothing articles such as, for example, a baseball-style hat or cap.Type: ApplicationFiled: October 8, 2008Publication date: February 4, 2010Inventor: Christopher L.
