Programme de Concert is a drawing in blue pastel on paper realized by Adolphe Willette in the Late 19th Century. Very Good conditions. Monogrammed. Including a cardboard Passepartout (65x 50cm). The artwork is depicted through rapid and deft strokes, masterly. This piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I take full responsibility for any authenticity issues arising from misattribution
