The stamps all include portraits of Jacques Cousteau:
50p - SP-350 Denise - Cousteau's 'Diving Saucer' - a two-man submarine built in 1959, and usually operated from his ship Calypso. It is capable of exploring depths of up to 400m (1,300 ft).
90p - Cousteau driving an underwater scooter - an electric powered machine he co-invented in 1954 to transport divers rapidly underwater.
£1.30 - A later more compact design of an underwater scooter.
£1.60 - The RV Calypso - Cousteau's main research research vessel. She was originally built as a minesweeper in 1941 for the Royal Navy, and served briefly after World War II as a ferry in Malta. Cousteau converted the ship into an expedition vessel in 1950. She sank at Singapore in 1996 due to an accident, but was refloated. There have since been various attempts at restoration.
