Clyda Rosen, born Vietta Taff in Israel was a popular topless model and porn star in the 1970s London pornography scene, renowned for her large bust.
Clyda was discovered in the early seventies by Harrison Marks, who used her both as a glamour model in his photography and as an actress in his 8mm films which at the time were being filmed in both hard and soft core versions. Some of the films Marks made with Rosen include Autograph Hunter, in which Clyda plays a groupie who breaks into the home of rock star Randy Tool, and Dolly Mixture, a horror spoof in which Clyda plays the female creation of a Mad Doctor who indulges in mammary sex with the Doctor's Hunchback assistant. The most famous of the Marks/Rosen 8mm films was Die Lollos (a.k.a. The Customs, Strange Customs) in which Clyda attempts to smuggle pornography through British customs. For years it was rumored that John Cleese played the role of the customs inspector in it, however it was subsequently revealed to be a look-a-like. Die Lollos was also filmed in a black and white soft core version called Unaccustomed as I Am with a different actor playing the customs officer. A third version of the film "Duty Free" has a different actress playing the Clyda role.
