Friedmann printed 50 portfolios, at least 24 of those (perhaps up to 44) are missing. Contained portraits of: Lasker, Réti, Grünfeld, Selesnieff, Euwe, Tartakower, Bogoljubow, Tarrasch, Spielmann, Rubinstein, Wolf, Walter, Bernstein, Teichmann. Printed on deckle-edge paper, all prints signed by the artist. The hand-written end paper of portfolio No. 27, once Lasker's own copy, is shown here as an example only. Friedmann wrote that he exhibited this portfolio in 1924 at Gallery Wenzel in Breslau. He probably also exhibited this portfolio in Berlin, Leipzig, Dresden, Hamburg, Munich, and other places, such as the Düren Rheinland Museum.
