Actually, Fratelli Toso did not do the Apparenza vases attributed to them by Leslie Pina, and by me on my website (I will correct this later when I return home from a trip).
They were actually done during the war in Naples. Murano just about shut down during the war, as Venice was being bombed, so a group of artists and craftsmen from Murano went to Naples and set up shop there. If you look at the largest Apparenza vase on my webiste, you will see the original factory label with the name of the factory. I had thought it was an import label until recently corrected by Sheldon Barr (author of "Confections in Glass.")
