At first simply titled Popeye, the publication mostly dealt with self-contained tales (unlike the original, serialized comic strip), usually featuring a longer lead story starring Popeye and a few shorter backups headlined by either Popeye or another character. Sagendorf even introduced new backup series such as Axle and Cam or Sherm! and equally used Segar's complement to the daily strip, Sappo, as the supporting feature in the book. One-page text stories would also be included, as well as the later "Popeye's Physical Fitness Program", with the format changing through the years.
