Pyrex Verde Pattern (olives) - from what I've read, c1967. I'm probably measuring wrong, but from tip to tip it is 13". This was a dish someone was throwing away about 4 years ago, which blew my mind because why in the world would someone throw away a perfectly good Pyrex dish?? - is in mint condition, no chips, nicks, like brand new. I welcome any additional or correctional information -- thanks!
