You know I wondered about that, but figured maybe at some point he did glass decorating plus when I tried to find "Jose Cirera Royo" the only info I could find related to items for sale & God only knows if they simply copied info thats an old wives tale from the past so figured there is no such person & maybe Cirera & Royo are actually two totally different people after all, but could not find anything related to a Jose Cirera, only a Jose Cirera (or Cire) Royo a Catalan artist of Catalonia Spain. The glass itself most likely from Gordiola Glass Works.
