Ardy:
It's a terrible picture, but it gives you some sense of the Harrtil range. I've included a photo of the Harrtil label as it's the only one I've found. I was going to say that Harrtil is not hard to find: you simply search eBay for Seguso Merletto, but that's less true now than before. I think we can that Mark Hill for that. BTW, I don't think eBay sellers were trying to deceive as the original mistake seemed to come from Pina's '50's Glass,' where she identified a Harrtil piece as Seguso. She corrected the mistake in 'Italian Glass.' If you want a picture of any individual piece, let me know and I'll send it to you by email.
