[Mark Twain (contributor)]. Gutenberg-Museums. Gutenberg-fetz zu Mainz im Jahre 1900. Zugleich Erinnerungs-Gabe an die Eröffnung des Gutenberg-Museums am 23. Juni 1901. Mainz: Hermann Quasthoff, 1901. First edition. Quarto (9.25 x 6.75 inches; 235 x 170 mm.). [4], 139, [1, blank] pages. Frontispiece. Publisher's perfect binding in the original light grayish-blue wrappers; all edges of the text block trimmed. Spine slightly askew; title written in manuscript on backstrip; spine ends very lightly worn; faint tidemark to the upper margin (continues throughout the text, though it's barely visible for the most part); wrappers very lightly soiled. Occasional very minor spot soiling throughout the text. Very good. First printing of a Mark Twain letter to Adolph Goerz discussing the invention of the printing press on pages 13-14 ("The world concedes without hesitation or dispute that Gutenberg's invention is incomparably the mightiest event that has ever happened in profane history"). The letter is in English, but otherwise, the text is in German. (#10194).
