Catalog 20 distributed in 1995 by the late San Francisco book dealer Steven Leiber. Folded tabloid format issue printed on newsprint and housed in an envelope. "Catalog offered primarily Eastern European performance art documentation and Latin American Mail/correspondence art. 'InterMedia: Special European & Latin American Issue' was an imagined issue (no.9, c.1979) of the periodical 'InterMedia.' Contributions had been sent to the magazine; however, the issue was never published. Most of the the works offered in Steven Leiber's catalog were those works submitted for publication in 'InterMedia' in 1979 (acquired through Harley Lond, the editior of 'InterMedia'). All eraser stamps used in the catalog were designed by Pawel Petasz (Elblag, Poland) and borrowed from Bill Gaglione (a.k.a. Dadaland, San Francisco) for use in this publication." -- from "Steven Leiber : Catalogs," Inventory Press, Los Angeles, 2018.
