Photo-illustrations throughout, with full-colour advertisements and reproductions of paintings of sailing ships, it was to be found in the saloons of numerous passengers ships of the day.

Lowry refers to reading the magazine in his first novel Ultramarine; "or reading The Blue Peter" (Pg. 111) "The copy of the Blue Peter on top of my heaped clothes" (Pg. 133). A possible source for many nautical references in Lowry's work and his knowledge of Joseph Conrad and Bill Adams whose work was published in the magazine.
