After Katrina I salvaged a full set of a great-aunt's dishes. They're stoneware in four pastel colors with grapes embossed on the rims and marked "Del Coronado - Made in California." I know that her daughter sent the set to her not long after WWII.
I've found very little information about them on the internet - most everything seems to point to Nasco or the Hotel del Coronado. I'd love to know anything further about them.
And now the battery on my camera is dead
I'll put up some pictures later.
