Advertising Japanese Kewpie Mayonnaise Design Proposal?

Description

Advertising Sign Japanese Kewpie Design Proposal? Found these signs at the estate of a Southern California designer. I believe these signs are proposal ideas as the top “Be A Star Chef_Alt” label is different on the different signs I found. Very cool looking, great for framing. Printed on 1/4” styrofoam type material.
Measures approximately 16 1/2” x 11 3/4”
Condition is "Used". Shipped with USPS First Class (3 to 5 business days).
