Marcel Duchamp's Boite-en-valise seems quite full. And it turns out from this
This leather case contains sixty-nine miniature reproductions of Duchamp's works. This is number two of twenty-four de-luxe versions of the case. Each of these features a different, hand-coloured 'original' fixed to the inside of the lid. The box 'unpacks' in such a way that some sections slide out, with other folders and black-mounted prints inside. For Duchamp there was no clear distinction between the original and the reproduction, a concept cleverly embodied in this piece. The case is also reminiscent of a travelling salesman's display case, containing a selection of Duchamp's pre-1935 work like a portable museum, made for his move to New York in 1942.
And here's a link to the Smarthistory Duchamp video made here at the Portland Art Museum. You'll hear Chief Curator Bruce Guenther and Smarthistory's Dr. Beth Harris discuss Duchamp and his work. Click here - it's about four minutes long.
