Yoko Ono was a supporter, but declined to bcome a member, of the early Fluxus movement. She embraced various dAdA ideas.
Her seminal book Grapefruit (1962) contained many references to the use of the mail to advance conceptual art, including the 'Portrait of Mary' below.
There are 28 'Mary's' currently members of IUOMA (including variations on the name such as 'Marya' and 'Maryse').
I thought that one Mary might want to take up Yoko's idea, perhaps adapting it to a simpler 'add-and-pass' format.
Go Mary's go!!
"PORTRAIT OF MARY
Send a canvas to a Mary in any country and ask her to paste a photograph. Have her send the canvas to a Mary of any country to do the same. When the canvas is filled up with photographs of Marys, it should be returned to the original sender. The name does not have to be Mary. It can also be a fictional name, in which case the canvas will be sent to different countries until a person with such a name will be found. The object to paste on the canvas does not have to be a photograph. It can be a numeral figure, an insect or a finger print.
From Yoko Ono, Grapefruit (1964)
