John Held Jr. (mailartist)

John Held Jr. (born 1947 in New York, USA), is an American mailartist, author and performance artist who has been an active participant in alternative art since 1975, particularly in the fields of rubber stamp art, zine culture, and artistamps. He is one of the most prominent and respected promoters and chroniclers of mail art.

Vittore Baroni has written of him, "He has been called the James Boswell of mail art and indeed, like the renowned collaborator of writer Samuel Johnson, John Held Jr is the best biographer (and bibliographer) that postal art has ever known or might ever have desired."
