Christo made his first packages and wrapped objects as part of a group called Inventory while living in Paris in 1958. Thus began the artist's distinctive career of wrapping, covering, draping, and folding fabric over, through, and around everyday objects and constructed and natural forms. He eventually extended this practice of using fabric to include large-scale urban and rural sites; since the early 1960s, he has collaborated on these outdoor projects with his wife Jeanne-Claude. Taking their work outside the confines of conventional exhibition spaces, Christo and Jeanne-Claude have maintained a creative independence that extends beyond galleries and museums. Christo is the sole author of the packages and wrapped objects, along with the studies for the outdoor projects. These works are the only collectable elements of his work, owing to the temporal nature of the outdoor projects.
The critic David Bourdon called Christo's work "revelation through concealment",  for by covering and hence concealing a form, whether recognizable or not, Christo endows it with meaning. Beyond actual forms, the artist's interests range from contemporary art practices to ancient stylistic devices to political thought. The compositional elements of Christo's enshrouded forms, for example, echo the drapery of classical Greek figural sculpture and Byzantine imagery, sources that trace back to Christo's native Bulgaria, which borders Greece and was once part of ancient Thrace. 
By extension, the fabric also alludes to the human body and to Christo's anthropological concerns. In discussing the medium, the artist cited a more contemporary and personal referent when relating the use of fabric to his Marxist background. He commented, "Friedrich Engels said that fabric made [modern] man different from primitive man...fabric is almost like an extension of our skin." 
Fabric has been the common denominator in Christo and Jeanne-Claude's work for over forty years, and has ranged in type from found materials to custom industrial weaves. The artists' formalist concerns embrace the properties of fabric: its folds, pleats, and drape, which are created by the ropes or lines that bind or support it. Beyond these physical dimensions, however, Christo and Jeanne-Claude's work infiltrates the social fabric of the time and place where it is created.
Package 1974 was made in New York City specifically for Dorothy and Herbert Vogel, whom Christo and Jeanne-Claude had met in 1971. Christo chose for this work an ocher tarpaulin he had acquired in 1968 as one of the sample fabrics for his proposal for wrapping the Museum of Contemporary Art in Chicago in 1969. While the projects and wrapped objects obscure recognizable forms, the packages often conceal ambiguous contents. This ambiguity endows the packages with an abstract quality that is engagingly ironic, given that they are packages and, as such, everyday objects.
In making Package 1974, Christo covered an undefined mass with tarpaulin and neatly bound it in rope tied in a horizontal, vertical, and diagonal orientation. The artist has said this sparse and predominantly rectilinear format was determined by the heaviness of the tarpaulin.  The pattern of rope in Package 1974, which is evocative of the minimalist grid of the mid-to-late 1960s, contrasts with that of Christo's more randomly bound packages, whose allover array of lines on canvas is reminiscent of Jackson Pollock's webs of paint.
