Quarto. (4)ff booklet + 1 original wood engraving + 20 sheets of engravings reprinted from their original blocks. As the printer, Andre Chaves, explains in his Introduction, the TBP was founded in 1937 in Mexico City as a direct response to social and political crises of the period. They believed strongly that the technical requirements of engraving, when married to artistic sensibility, could directly confront the waves of imperialism and fascism, and could illuminate and elevate those trapped in poverty and cycles of underdevelopment. Their images certainly bear out the cause, adopting the neorealist style that would only take off in European countries after WWII had ended. Often they depict scenes of industry contrasted with an untouched countryside and/or the dignified complexion of a worker. Members represented include Alberto Beltran, Elizabeth Catlett, and Leopoldo Mendez. The additional engraving is printed on laid paper and signed by the artist, Francisco Mora, at the reverse. Booklet bound in printed white paper wrappers, and held with all other materials in printed four-flap portfolio showing only scant rubbing. Fine.
