As this is in a Table Ware catalogue, I guess it is just a 'novelty shape' item. Of the ten spirit bottles/flasks on that page, three are novelty shapes. Of the 80 decanters on the site so far, only these S&W ones have novelty shapes. Those in the Moser catalogue (1948) certainly are the most interesting from a design perspective. Once I finish uploading the S&W catalogue I will be concentrating on the cut glass catalogues first so that Kristi has material for her categorisation project available, first American, then German, French and Belgian. If I come across any more novelties like the above I will add the thumbnails to this thread.
