I think this was the first ever piece of old glass OH and I bought, c. 1994-95. It came from a dealer in our region of Victorian 'fancy glass'. She told us it was a Sowerby jug, and she certainly had a lot of other Sowerby items on sale, all of them pressed glass, with some Walter Crane designs among them. We didn't much care for those, or the twirly free-blown stuff from other sources, but this little jug called out to us. The dealer really didn't want to sell it, and evidently regarded it as special, because whenever we saw her for years afterwards she would ask, "And are you still looking after my little Sowerby jug?"

I'm waiting for the County library to dig out their copy of Simon Cottle's book on Sowerby glass, just in case I missed anything the last time I read it. It doesn't really look like the Venetian ware, but presumably the firm made other free-blown glassware before they specialised in the pressed stuff?
I found it impossible to place the jug safely to photograph the pontil, by the way.
