Henri-Gabriel Ibels (1867-1936) Illustrations for Théâtre Libre programs. 1892-1903. Lithograph. Each [350x390mm]. Printed in color. Very fine proofs on white laid paper, without the letter. Good margins. Set of 4 p. Although these proofs are commonly considered "avant lettre", the subjects show significant variations from the published programs. They are the result of a transposition of the subjects onto other stones or zincs, probably posthumous in view of the mid-twentieth-century paper.
