Yep, my trip was awesome. Saw loads of glass. Made it to Passau, which was extraordinary.
It seems that most of these "Etruscan" style designs were done with transfer prints, or a combination of transfer and painting, regardless of manufacturer. Although the two images on Alissa's matching vases are slightly different, I'm betting that they are at least partly transfers.
The design shown in the book is apparently exactly the same as the one in the OP, just a mirror image. The vase it's on is very similar in coloring, too, though not quite the same shape. Unless the English and Bohemians shared transfers, I think it's safe to say this is Harrach.
