I am not sure which company made your pitcher, but it isn't Fratelli Toso. The style of the millefiori isn't one they used. Two companies that did many things like this are Bucella and Campanella, but there were others, too. Many of the millefiori pieces can be hard to attribute once the label is off. Does it have gold peppered over the surface? It doesn't look like it does, but I thought I would check.
