The institute wanted to promote their new standard by having advertisements and other items being printed in their format. They thus approached influential businessmen to adopt their standard. One of these was Ludwig Roselius, founder of the Coffee Hag company. Roselius approached the heraldic artist Otto Hupp and together they started a large publication on German (and later foreign) arms of towns, cities and villages (known as the Coffee Hag albums). In the Coffee Hag packages coupons were added, for which one could obtain stamps with the arms of a town or city. These stamps could be glued in the albums. The stamps were printed in Weltformat V, the albums in Weltformat IX. These standards were also mentioned on the stamps and in the books to promote the idea. The series were issued long after the Brücke was abolished, and in the second edition of the German albums the referral to the Weltformat was removed. The size of the stamps, however, remained identical in all European albums until the 1950s. The Swiss stamps still used the text Weltformat V until the mid-1920s.
