Interior design magazines often show retro style as an interior decoration of mixed styles and objects from the past, second hand and new. For example, 1970s patterned wallpapers, combined with second-hand furniture from the 1960s and 1950s. The value of old artefact has increased because the object used to be considered old-fashioned and everyday.[16] In this case ‘retro’ indicates a value and that is also partly why today’s retailers produce new objects in an old style.
