Softbound; B&W illustrations and photos; 88 pages "Current editions of the "Speedball Lettering Books" are at #21. #7 was produced in 1923 and a new edition was produced about every four or five years. It is difficult to say which one of the group is the best as elements of one book migrated into newer books over the years. Still, as a group, they contain some outstanding artwork and design ideas. Due to their accessibility, many sign painters acquired the books and used them constantly." -from signmuseum.com via The Wayback Machine
