Retro colored plastic picnic tray divided plates and cups, 50s vintage

Cute 1950s vintage plastic picnic dishes - six divided tray style plates and four cups, in great retro colors - deep green, coral pink, grey and chartreuse!

The plates measure 12 3/4" x 8 1/4" and have some slightly discolored scratching from use. The mugs are 3 1/2" tall, all look very good without staining or discoloration.

The colors seem to be a perfect match, though the plates are marked Amerline - Chicago and the cups are marked Peoria.
