In addition the albums also contained a 17-page introduction to heraldry, with numerous examples from the Belgian towns. These were referred to by their numbers. The second edition has the same text, but the numbers and examples have been updated with the newer stamps. The date on both texts, however, is February 1930. The text was written by Fidèle-Gabriel, a priest who also illustrated the book on the heraldry of Belgian provinces (issued in 1919 Dutch and in 1921 in French and written by E. Gevaert).
