Set of 2 Porcelain Enamel Metal Serving Snack Trays: Green & Blue Mid Century

Set of 2 Vintage Porcelain Enamel Metal Serving Snack Trays in Light (lime) Green & Light (baby) Blue MCM / Mid Century. One very small chip on edge of blue tray (see pic) and green tray's enamel is dull in some spots. Overall - very good condition for their age. Trays like these used in schools / hospitals, etc, back in the late 50's and 60's. Back of blue tray reads: Compliments U.S. Porcelain Enamel Los Angeles. Back of green tray reads: Quality snack platter Los Angeles patent pending. Very unique pieces! See photos for condition of items and pics serve as part of the description.
