Christo and Jeanne-Claude

See their work
On Visipix: On their official website with excellent photos of Wolfgang Volz:
The two artists are famous for environment art, especially wrapping things from wine bottles to very large buildings, marking islands and Central park.

They finance all these enterprises themselves with the sales of drawings, lithographs and other objects. The taxpayers pay nothing but they benefit substantially from the public attention.

Here is an example of a lithography of Christo and Jeanne-Claude as advertised by an Art Gallery:

On January 22, 2003 Michael R. Bloomberg, Mayor of New York City, announced that the city has given permission to New York artists Christo and Jeanne-Claude to realize their temporary work of art:The Gates, Central Park, New York, 1979-2005. For those who will walk through The Gates, following the walkways, and staying away from the grass, The Gates will be a golden ceiling creating warm shadows. When seen from the buildings surrounding Central Park, The Gates will seem like a golden river appearing and disappearing through the bare branches of the trees and will highlight the shape of the footpaths. The 16 day duration work of art, free to all, will be a long-to-be-remembered joyous experience for every New Yorker, as a democratic expression that Olmsted invoked when he conceived a "central" park. The luminous moving fabric will underline the organic design of the park, while the rectangular poles will be a reminder of the geometric grid pattern of the city blocks around the park. The Gates will harmonize with the beauty of Central Park.On January 3, 2005, weather permitting, our professional

workers will enter Central Park. Using forklifts and pallet jacks, they will place the 15,000 steel weights bases at their specific positions on the edges of the walkways, usually at 12 foot intervals, unless there are low branches. On Monday, February 7, 2005, weather permitting, approximately 700 non-skilled workers (in teams of 7) will elevate The Gates assemblies -- 2 vertical and one horizontal pole, the upper and lower aluminum corners and base assembly and the fabric panel in a cocoon, attached to the upper horizontal pole. The fabric panels will not initially be seen because they will be restrained in the cocoons which will remain closed until Saturday, February 12, when all the cocoons will be opened, in one day (maybe in one morning), weather permitting, as with all our projects. The Gates will remain in Central park for 16 days, then the removal will start.
