Three scrapbooks covering Carter’s trip to the International Congress of Master Printers in Gothenburg Sweden, June 4, 1923, and his subsequent travel in England, Sweden, Norway, Denmark, Germany, Czechoslovakia, Austria, Switzerland, Holland, Monaco, and Belgium.  Correspondence relates to the purpose and results of the International Congress of Master Printers, government reimbursement for trip expenses, travel plans, personal observations, daily affairs of the Government Printing Office, and letters of introduction for Carter. Correspondents include Wilbur Carr, J. Linton Engle, Edmund G. Gress, Warren G. Harding, J.R. McCarl, Charles Stephenson Smith, J. Thomson Willing, and Wald Zachrisson. There are 65 letters in the scrapbooks.

Letters and newspaper clippings throughout the collection reflect some of the European unrest following WWI and are helpful collectively in aquiring an informal impression of the period. The scrapbooks relate more specifically to the history of printing. In addition to the published Proceedings of the Congress, the scrapbooks contain material relating to the Eleventh Cost Congress of the Federation of Master Printers and Allied Trades of the United Kingdom, the Johannes Gutenberg Memorial in Mainz-am-Rhein, and the Plantin Museum (the 16th century print shop of Christopher Plantin) in Antwerp, and the series of letters between Carter and his secretary, Mary A. Tate, concerning the daily affairs of teh Government Printing Office during his absence. The remainder of the scrapbook contents is made up mainly of tourist literature and personal souvenirs of the European tour
