PUBLICATION AND ISSUE SECTION
Mark description
The mark consists of a design of a standing brown bear, wearing a red t-shirt that reveals half of the bear's stomach. On the shirt is a gray oval with white shading to the left of the Greek character for "S", or "SIGMA", in white. To the right of that is the wording "OPTOSIGMA" in white. The bear's palms, ears, snout and stomach are in beige. The bear's eyes are white with black pupils with a white circle in them. The bear's nose is black with a white line and circle that represent shading on the top. The bear is smiling, with the smile depicted in dark brown.
