new w/ label vintage Polish pottery blue waves Unikat 1383 pie pan or quiche dish Danuta Knapik

Blue waves pattern Polish pottery pie pan about 10" in diameter, in very good - never used - condition. There's a few crazing lines, no damage or wear.

This is signed D Knapik, Unikat 1383. I was told this is one of the old, discontinued patterns. Very pretty!
