As well as being Armstrong's home, Cragside acted as an enormous display case for his ever-expanding art collection. The best of his pictures were hung in the drawing room, but Shaw also converted the museum into a top-lit picture gallery. Pride of place was given to John Everett Millais's "Chill October", bought by Armstrong at the Samuel Mendel sale at Christie's in 1875. Armstrong also bought Millais' "Jephthah's Daughter" at the Mendel sale. Both were sold in the 1910 sale; "Chill October" is now in the private collection of Andrew Lloyd Webber, and "Jephthah's Daughter" is held by the National Museum Cardiff.
