He is best known for his collections of irons, shoes, and other objects[n 1] in the sociological art movement of the 1970s.
As a youth, Thierry Agullo was interested in typography and publishing and had an apprenticeship under Robert Morel at Soleil Noir.
In 1965, he began to collect used irons, which he exhibited for the first time in December 1972 – as well as wallets, purses, and gloves.
In 1974, he met the artist Pierre Molinier, who became a colleague as well as a close friend.
Their friendship resulted in two series of photographs: L'Indécence, 110 black and white photographs produced as a limited edition book by the À l'Enseigne des Oudins gallery in 1975, and Thérèse Agullo on the theme of androgyny, created in 1976 just before the suicide of Pierre Molinier.
In 1979, he was editor of a posthumous collection of poems by Pierre Molinier, Les Orphéons magiques, written between 1946 and 1950.
