Las flores del vicio

I was in Spain when this was filmed with my family. The film was shot in the town of Mojacar in the early 1970's. I met most of the actors and knew Silvio Narizzano and his partner Winn Wells personally since they lived down the street from our home. My parents owned a bar/restaurant called El Saloon and all the actors spent a great deal of time in their establishment during filming. My brother was cast as the mentally challenged child who was stomped to death in the plaza as a woman looked on from a balcony.

I clearly remember the shot, however I have never seen the movie as I was quite young at the time. I would like to obtain the movie (dvd, video). If anyway can tell me where to purchase that would be great.

Thank you.
