the great marvel series
by Roy Rockwood

"Since the days of Jules Verne, tales of flying machines and submarine boats have enjoyed increasing popularity.
Stories of adventures, in strange places, with peculiar people and queer animals, make this series noteworthy and popular."
From a Couples & Leon advertisement.

Roy Rockwood was a popular Syndicate house name and was used on Bomba the Jungle Boy, Dave Dashaway, The Speedwell Boys, and other publications.

One of the first products of the Stratemeyer Syndicate and its earliest venture into science fiction.
This series is somewhat of an oddity due to the huge time gaps that occurred between the release of volumes 6 & 7 and volumes 8 & 9.

All volumes originally published by Cupples & Leon.
Each volume had a full color dustjacket and the the cover was also illustrated. Variations in the number of colors used on the cover printing have been observed.

Authors:
#1-5 and #8 Howard Garis

In the late 30's or early 40's, Whitman Publishing Company reprinted volumes 3, 4, 5, 6, 8 and 9. New dustjackets were designed and the illustrated bindings were eliminated as were the internal illustrations.

In the mid-30's, Cupples & Leon released a 4-in-1 book, Mystery and Adventure Stories for Boys, containing the first story of this series along with Billy Smith - Exploring Ace, The Boy Ranchers & Baseball Joe Of The Silver Stars.
