Rock Drill (Jacob Epstein) Rock Drill (Jacob Epstein) Rock Drill (c. 1913–1915) and the associated Torso in Metal from Rock Drill (c. 1913–1916) are Jacob Epstein's most radical sculptures. "Rock Drill" comprises a plaster figure perched on top of an actual rock drill. The combination of an industrial rock drill and the carved plaster figure makes the artwork an example of a "Readymade" created at the same time as Marcel Duchamp's "Bicycle Wheel" (1913). A 1974 reconstruction, by Ken Cook and Ann Christopher, is part of the Birmingham Museum and Art Gallery's collection. "Rock Drill" has been heralded as embodying the spirit of "radical

Published in Zug, Switzerland, this 91-page hardback book, part of a series on the leading architects of the day, was titled "Some recent work of Philip Hepworth". It was illustrated mostly with black-and-white photographs of the buildings designed by Hepworth. The embossed clothbound cover shows the Roof Garden House in Bickley, with the cover artwork described in 2015 by RIBA's British Architectural
