UniSquare Item ID:
PAIR of Chicago 1933 Worlds Fair Hot Pad Trivets Transportation Train Plane Car Ship
They measure approximately 10" x 7" and 8" x 6"
I love the detail of these and how they show so many different types of transportation. Really cool pieces.
They have a slight curvature to them as well as a slight bit of foil loss as I've tried to show in the photos.
