I am working on analyzing some artifacts from the Charnley-Persky House in Chicago, designed by Louis Sullivan and then-draftsman Frank Lloyd Wright and built in 1892, so the site has materials from the 1890's to the present.
These artifacts are from a mixed context.
Any information about them would be really helpful.
