This item has spent a lifetime being used for the purpose of its creation with the original artist/user. Signs of this life lived heartily may be present on the piece in the form of stains, thread loss, loose threads, holes, tears, color run and other imperfections. Therefore the condition must be assumed to be “not” perfect. More photos of such imperfections will be provided on request.
