the emblem of 20-30 international was an hourglass, symbolizing the passage of time and the need of young man to take advantage of his time and energy for useful activities. around this hourglass, there were four "s". the four "s" have a double significance since these were the initials of the first four 20-30 clubs (sacramento, stockton, san bernardino and san francisco) and they also form the initials of the original slogan "sincerity in service, our slogan for success".
