This mint condition quiche dish is by one of the preeminent porcelain manufacturer's of the 20th century - Villeroy & Boch.
This pattern is called "Naif". The Naif line grew to include a "boutique" line that features various country scenes. This one features a Noah's Ark theme with Noah on the ark on deck showing a lion, bear, pig, baboon, flamingo, elephant, sheep, cow, a giraffe, and a hippo. Where a mast would be is a huge tree that shows flora and fauna and flying creatures. The water shows schools of fish. The dish is 9 1/2" x 1 1/2" and has the typical crinkly, scalloped rimmed sides and a very white ground. Our research shows that this dish came in 3 sizes. One slightly smaller and one slightly larger than this. It is very fairly priced here.
We considered this a really nice "quality" find. It just needs a quiche-baking family to find and take it home. Priced reasonably to allow you to do just that! It would also make a great gift.
