Benedict Schwartzberg letters

Fascinating set of 2 envelopes sent to Tjeerd Deelstra by Benedict Schwartzberg from New York in 1969, both contain 3 copies of the same pamphlet with intense typewritten poetry starting with 'I am God'. Apparently an abridged copy of a full version free on request. The author also placed advertisements for his free 'huge 10-page leaflet (creation, religion, names of god, numbers (...) cigarettes, bibliography). Part of the text appeared in The Avatar No. 9 1967.
