Dutch architect (1890–1963). ALS signed “Oud,” one page both sides, 8.25 x 10.25, May 11, 1925. Letter to Alfonso Ianelli. In part: “Thank you so much for the interesting book of Sullivan you sent me so kindly. I always heard of him and hardly ever saw something. I am glad to know his work better now: he was a master of ornament and in the same time strong and severe in his conceptions. I also was glad to see some of your works in a revue I think M. Byrne sent me: so fine the connection between the modern workers of U.S.A. and Holland staying upright…I sent you a volume of ‘Wasmuth’ with some of my works. I have later work in preparation now of which I once hope to send you the plans: theatre and schoolbuilding.” In very good condition, with central horizontal and vertical folds, overall light dampstaining, and some mild spotting.
