This stool was designed by Man Ray for Gavina's Ultramobile Exhibition. It can be used 'eye' down as a regular stool, vertically as a rocking stool, or 'eye' up as a coffee table. It can also be used simply as a work of art. I have official proof of authenticity such as vintage catalogs, designer records, or other literature sources and take full responsibility for any authenticity issues arising from misattribution
