Although the diamond thumbprint description is an accurate one, it would be misleading to sell your wine jug as the EAPG Diamond Thumbprint pattern. You might use thumbprint or bulls eye or even diamond with thumbprint specifying that it's cut, and not EAPG. This is probably a century later than that 1850 heavy rather primitive pressed pattern. Some of these are Italian and I'd guess are still being made, although I haven't seen any with this cut pattern. DoRi
