70s vintage tortoise shell plastic dishes, retro summer serving pieces

Unmarked 70s vintage tortoise shell pattern dishes, acrylic plastic, I think, rather than melmac?

This lot is some great serving pieces - a 12" divided relish tray, a round serving tray 11" in diameter, a 32 oz cocktail pitcher 10" tall, a 10" salad or potato chips bowl. (There are also four individual salad bowls which we're including, but one of these has a crack so it's not really a full salad set.)

Everything else looks very good, very little scratching, no chips or cracks.
