I respectfully disagree, Floor. Massively! The difference between lampwork from Gablonz and Venice can only be measured by lightyears!
Not that proof is really needed in my opinion, but the beads you posted (right side) are proof of that. Any beginner is able to make such pieces. Unfortunately I cannot see the sample-card very well, but the card seems to show simple beads with a Millefiori cane.

Anybody else thinking Gablonz was an equal lampworker in comparison to Venice? Surprise me!
