since everything since the invention of the wheel could be considered a copy and variation of something done previous, Franchini copied the ancient bead makers and brought the art of picture canes to its absolute zenith in the history of the art at that moment in time. Others have done well with the art also. I wonder if the makers of the articles with the more recent face and picture canes were attempting to copy Franchini? I don't recall seeing an assortment of Franchini "trade beads" but there are numerous examples of the more recent faces appearing on all types of beads. Also I think the faces on the beads are some incredible works in their own right, "poorly" just doesn't describe these little works of art. Until the past few years there have not been any glass artists that could compete with even the "poorly" "copied" examples and even these modern versions are lacking the character of some of the varieties on the perfume bottles and beads.
Just my opinion....
