Lettre autographe signée adressée à Jani Brun

Autograph letter signed by Philippe Sollers addressed to his friend Jani Brun (9 lines in blue ink) apologizing for having been unavailable for health reasons: "... la vérité c'est que j'ai été supper-grippé (à 40°)... à plus tenir debout ni rien avaler..." ["... the truth is that I've been super-sick with flu (at 40°)... couldn't stand up or swallow anything..."] but that he will not fail to let him know when he feels better soon as he is still convalescing.
Central fold inherent to the envelope.
