Karel APPEL (1921-2006). L.S. with autograph compliment, Paris May 18, 1979, to translator and critic Frédéric de Towarnicki (1920-2008); 1 page in-4 dactyl. "The 3 volumes I'm working on on CIRQUE will soon be quite finished". He thanks him for his continuous collaboration over more than a year, "both as regards the text (translated into English) and the collaboration for the titles of the engravings and the spirit of all our work. Thank you for all this effort". He will soon receive a copy of each of the volumes, "i.e. all 30 engravings [...]. I hope to see you soon, as I'm feeling ill at the moment".
