Billet autographe signé adressé à Jani Brun

Autograph note signed by Philippe Sollers addressed to his friend Jani Brun (6 lines in blue ink) informing him that he is overwhelmed: "... pas mal de contre-temps etc..." ["... quite a few setbacks etc..."] but suggesting the possibility of an appointment for the weekend, in which case he will not fail to notify her: "... si oui je te fais signe samedi matin... Excuse-moi..." ["... if so I'll let you know Saturday morning... Forgive me..."]
Envelope included on which Philippe Sollers has simply indicated the surname and first name of his correspondent, a date indicated in pencil, probably that of the receipt of the note by Jani Brun.
Central fold inherent to the envelope.
