When most people look at an egg cup, apothecary jar, spool of twine or metal baking round, they can’t see beyond its original use. But in the hands of Becki and Jur van der Oord of Installations Antiques, such inconsequential pieces are reexamined, then artfully composed into stunning, unexpected Joseph Cornell-esque assemblages. Small wonder, then, that their Heights-area shop — the equally imaginative rebirth of a 100-year-old warehouse — takes us through the looking-glass into a world filled with new-use treasures. Such juxtapositions as glove darners, natural science specimens and spectacles create a tableaux of restrained color and form, which philosopher Horace called “poetry without words." We concur.
