Bought these together ages ago, and just found them in the bottom of a box today.
Not entirely sure they 'belong' together, as they're different colours and have different shades of opaque blue to the rim. The glass of the tankard is quite seedy, and the pitcher less so - but they both bear obvious tooling marks.
They're the same height (17cm), and both are finished off with a polished pontil mark. The pitcher has a LOT of base-wear... the tankard less so, but it is much lighter in weight.
Thanks for taking a peek.
