Spanish website todocoleccion.net sells a lot of old vintage magazines and magazine pieces from 1970s Spain. Here are some of the discoveries. Found in the WWW. Sorry, available only in lower quality like on lot of magazine selling pages. The magazines are from the years 1975 and 1976.

The woman above with the guitar is Spanish actress and model Roxana Caskan or Rosana Caskan.or Roxan Caskan. She wears a top that may be a blue jean vest.

In the early 1970s she has also been photographed wearing some kind of denim vest:

Next woman is Spanish singer Jeanette, famous for her single song PORQUE TE VAS. She was pictured more than one time with that blue jean vest while the year 1976 and wore it also on the single cover and while a tv performance.

Next woman is Spanish singer Marisa Medina, who seems to wear a denim vest while a magazine home story too.

Last attention belongs to Johnny Holiday and a blonde woman in his arms, wearing something, that maybe looks like a sleeveless denim piece.
