The glass vase was designed by Hubert Gessner in 1902 for Bakalowits. The decoration to the glass vase is illustrated in the Loetz book as probably designed by Koloman Moser. We cannot find an illustration of this particular piece but it may have been the product of a collaboration between the architect Gessner and Moser.
