A lesbian bondage and discipline story. Mario's art features gagged and trussed women subjected to unique bondages (bound to cannons, weighted with cannonballs), and torture devices on a Spanish galleon. Mario was a fetish artist who worked for a short period of time for Irving Klaw. He drew two complete serials for Klaw -- "Captives of the Scientists" (1954) and "Prisoners of the Inquisition" (1955) -- and an unfinished piece called "Rubber Queen's Captives" (1957). All three stories were reprinted in their entirety in Belier Press's Bizarre Comix #6.
