The mark consists of the stylized letters and symbol "Ch*lk U" with a stick-figure person hanging from the letters "h", "l", and "k". From left to right appear an upper-case letter "C", a lower-case "h", an asterisk symbol, a lower-case "l", and a lower-case "k". An upper-case "U" appears following and spaced apart from "Ch*lk". A stick-figure person appears to be hanging from "Ch*lk", with one leg attached to the bottom of "h", one arm attached to the bottom of "l" and one arm attached to the bottom of the "k". Each element of the mark is stylized as if written in chalk.
