Vintage 1940s Coronet Haskelite Lithograph Lap Trays Flying Swans Set of 5

GUC Vintage with normal wear for their age. Some edge wear and light scratching (see photos) Set of 5 trays These trays are so fun and unique! They were made by the Haskelite Coronet company. They are made of lightweight wood with lithograph paper on top. Clean only with a slightly damp cloth. I looked up photos to date these and came up with the 1940’s. They depict 3 swans flying over willows. They measure 16 1/8 inches by 7 1/2 inches. So fun and rare!
