While it's not "four and twenty Blackbirds" your baking can come close with this vintage porcelain casserole dish from Lourioux of France featuring a flock of six songbirds within, Waxwings among them. The dish measures 11.75 inches in length from handle to handle, is 6 3/8 inches wide and 1 3/8 inches tall on the side (1 7/8 inches at its upturned handles). It's in great condition save for some wear to the gold along the edge and is marked Fireproof Porcelain, Le Fauna, Lourioux, Made in France on the bottom. Please note there is a line on the very bottom that looks like a crack but isn't. I believe it was from the original firing.
