The top and bottom of the lunch box on the early years have
embossed depictions. This embossing created an early and primitive
3D effect of the depiction on the lunch boxes. The embossing can easily viewed on the box in my photos. Both the metal top and bottom contain embossing. When you look at the interior photos you will see the lid and the bottom embossing is clearly present.
Furthermore only the earliest versions also in included the "Nation Council Safety" information printed on the inside of the top lid. Its shown in the photos as well. Later year lunch boxes have only flat metal depictions on the top and bottom panels and no council information. The embossing process was costly was abandoned shortly after 1958-59 do to manufacturing cost issues, making the embossed boxes far more rare.
This box is as from a long past generation. It carries all the dings nicks and scars of the 60 plus years of travels and adventures over my lifetime. It has been with me all these decades. Made every move with us around the country, crisscrossing America and watching my children grow up. My collection has always had a prominent shelf in my home office over the past 40 years. When working from home and it was shit business day, sitting at my desk, seeing my collection scattered about my office, always brought back calmness of a simple time, but now its time to move them on to a new collector to enjoy and admire.
Authentic, vintage pieces of a long past generation will not be cheap. Send me an offer and find out if this will be yours.
I am sure the above helps to explain the rarity and uniqueness of the lunch box you have selected.
