THE WHITE FASHION
Very few dive gears were manufactured in white color; one that I remember is the Rio mask in 1969 of Technisub and few accessories, nothing else. Instead in the USA there was a company that already in 1964 produced fins and masks only in white, white which among other things brought out the amber shade of the glass with which the masks were supplied as standard. As we can see in the Globe Riviera catalog published this month in the Complete Catalogs section.
In 1959, U.S. Divers proposed for snorkeling an extremely complicated mask, with three-point headboard, dedicated to the person who wanted everything. In fact, it included a central snorkel facing back for nasal breathing, and a second snorkel to the right for mouth breathing. The latter was inserted into the central one near the valve, which guaranteed perfect sealing in any position. You can see it on page 14 of the "Divemaster" catalog of that year
