Description : Close up inspection indicates a contamination between the protective outer plastic cover and the printed material on the inside has digested a small amount of the glue in the surrounding area. Based on the splatter pattern, I think what we see here is the result of a human sneeze. The small facial or nasal hair found under the microscope ad credence to the theory.
