Jaap van Dam (1876-1972). "Proloog. Doek"
Gouache, 13 x 20.5 cm, signed with pen lower r. and titled lower l., mounted on cardboard with head margins.
Beautiful futuristic design. The big exhibition in 1934, for which Jaap van Dam built the enormous "Oud Venetië" complex, was illuminated by Philips sodium-vapour lamps - this was the first time these lamps were used. This drawing probably depicts this type of lamp.
